Chapter 17 Hardness Testing


When Zhao Guoyang was arguing with this stationmaster Xiao, some employees of the Siyang Group Inspection Station also came out of the warehouse to see the excitement.

To be honest, the average employee usually doesn't have a good impression of this stationmaster Xiao, and they know this person's character very well, but because he has a background, they don't dare to say more.

At this time, I saw a young man who looked very handsome and angry with him, and I was a little gloating in my heart.

Seeing that the number of people around him gradually increased, Ma Jian frowned and secretly complained bitterly.

He is engaged in sales, and he has always been accustomed to being kind to people, and what he is most afraid of is to have disputes and contradictions with others, not to mention the top supporting manufacturers.

But just now Zhao Guoyang's meaning is very clear, there is no problem with the quality of the frames provided by his factory, and this stationmaster Xiao is making trouble unreasonably.

For Zhao Guoyang, a young man, Ma Jian still trusts him very much.

At this time, the arrow was on the line, and he had to send it, and he could only hope that Zhao Guoyang could say that he was ugly and ugly, so that the other party could find fault with it.

Unlike Ma Jian's heart, Zhao Guoyang completely ignored the crowd that surrounded him.

He confidently pointed to the frame behind Stationmaster Xiao and said, "It's useless to say more, Stationmaster Xiao, do you dare to make a bet with me, just bet on whether the frame behind you is qualified or not." ” "Hmph, Shunxin Machinery Factory is our Siyang Group's old supporting factory, the product quality is absolutely passable, I don't dare to bet with you kid, do you want to bet on what you can afford to lose" Xiao stationmaster said with a disdainful face.

Zhao Guoyang said noncommittally: "Okay, just have your words" "So, together we took the frame to the site for inspection.

If the test results are really the same as I speculated, the main body of this frame is made of the wrong material, then please ask Section Chief Xiao to follow the rules and let the frame of our factory be put into storage first. ” "Of course, routine testing after warehousing is essential.

If our frames are not up to standard, then we will immediately pull these frames away and apologize to you. ” "Stationmaster Xiao, you also saw it, our horse factory director is here, you shouldn't have to worry about us going back on our word."

"Okay, just do as you say.

If what you said is not right, if there is no problem with this frame of Shunxin Machinery Factory, don't blame me for driving you out.

Stationmaster Xiao said indifferently.

Zhao Guoyang said happily: "Of course, if I am really wrong, you don't have to rush, we don't have the face to stay in your factory anymore." ” After Zhao Guoyang made his statement, the people watching the lively Siyang Group inspection station next to him turned their heads to each other.

"This young man is not very old, and his tone is quite big, but he really looks so imposing."

"Well, who said it wasn't, it's really rare for young people to dare to say and do it, and their factory director doesn't seem to be as tough as him."

"But he said that there is a problem with the frame of Shunxin Machinery Factory, this is unlikely, Shunxin Machinery Factory is a well-known brand in our southern Guangdong Province, and the scale is not much smaller than our Siyang Group, right, Lao Zhang."

The man known as Lao Zhang pushed his reading glasses and said slowly, "I don't know much about this."

However, just now I listened to the words of this posterity, saying that the main material of this frame is used in the wrong way, and the No. 20 steel is used instead of the usual Q235 steel. ” "As you know, I've been an inspector for 20 years, so I naturally know the quality of steel.

This No. 20 steel is obviously more expensive than Q235 steel.

If Shunxin Machinery Factory really uses No. 20 steel as he said, isn't it better than Q235 steel, I really don't understand this. ” While the onlookers were talking, the stationmaster Xiao had already instructed the young man from the two inspection stations to carry the frame into the warehouse and go straight to the inspection site.

Siyang Group's inspection field is quite standardized, and the inspection material machine is imported Germanic desktop Rockwell hardness tester, and its performance is absolutely good in this era.

Seeing this machine, Zhao Guoyang's only worry was quietly put down.

He knew that with such advanced equipment, it would be 100% possible to test the correct results.

The two young men at the inspection station put the frame on the material inspector, fixed it in front and back, left and right, and then said hello to Station Master Xiao and signaled that it was time to start.

Zhao Guoyang clasped his hands on his shoulders and calmly watched Stationmaster Xiao activate the material inspector over there, his face was calm.

Ma Jian, who was nervous on the side, saw this guy so calm, and couldn't help but gently poke him with his arm and said, "Hey, Guoyang, your judgment won't be wrong, if it's wrong, our trip will be in vain." ” Zhao Guoyang turned his head and smiled at the director of the horse factory and said with relief: "Don't worry, the director of the horse, I will definitely not be mistaken."

Although the material of the frame in his hand is better, it has a fatal flaw. ” "It's ridiculous that this stationmaster Xiao didn't know anything about it, and even praised the other party to the sky" When Zhao Guoyang and Ma Jian were talking in a low voice, the material inspector over there had already begun to work.

The Rockwell hardness tester is designed according to the principle of Rockwell hardness test, and only needs one side to contact the sample to test the hardness of the metal.

Relying on magnetic force to adsorb the Rockwell hardness tester probe on the surface of the steel, the material of the finished steel can be tested without supporting the specimen, and its accuracy is fully in line with the international standard ISO6508 and the national standard GBT230.

The principle of this desktop machine is very simple, that is, the hardness tester is fixed on the surface of the steel workpiece by using a magnetic chuck, without support, no sampling, no need to move the workpiece, and the test can be completed as long as one side is contacted.

The test results came out quickly, and the hardness of this frame was: HRB131156, which was within the hardness range of No. 20 steel, while the range of Q235 steel was between HRB657703, which was obviously not compliant.

Looking at the printout results brought by the people below, the muscles at the corners of Stationmaster Xiao's mouth couldn't help twitching, but he was not such an easy person to admit defeat.

Holding this piece of paper, this stationmaster Xiao pretended to walk calmly to Zhao Guoyang's side and said: "Count your kid lucky, you are actually right, the main body of this frame is indeed made of No. 20 steel with better performance." ” "How about it, I'm right, Shunxin Machinery Factory is real, without our explanation, directly used better materials.

Those who are engaged in production and processing know that the price of No. 20 steel is higher than that of Q235 steel, and now what else do you have to say. ” Listening to this guy's pure nonsense, Zhao Guoyang almost didn't laugh out loud.

He barely held back a smile, turned his head to Ma Jian beside him and said, "Director Ma, I think let's go back."

The Siyang Group wants to hit the street by itself, so we don't need to be implicated in the back."

Zhao Guoyang's words not only offended Stationmaster Xiao, but also offended the employees of the surrounding Siyang Group.

At that moment, some people were dissatisfied, and the old Zhang before said with a calm face: "Young man, what are you talking about, why do you want to hit the street by our Siyang Group, aren't you cursing people?"

"It's just that the young man is not sensible, and the one next to him looks like a leader, how can he follow behind and coax, I have never seen anything like this."

"That's right, he didn't speak for a long time, and he kept a sinister smile on his face, and he wasn't a good person at first glance," the person next to him said
