Hardenability of p235gh steel application after quenching and tempering

Pageviews:

The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy P235GH steel application products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of p235gh steel application stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.

C45 steel heat treatment: Quenching has low hardenability, and it is easy to cause uneven hardness of the drill rod during heat treatment, resulting in deformation or even cracking. The hardness after quenching is about 42 degrees, which is much lower than the 55 degrees of 42CrMo brazing rod. Therefore, the wear resistance is extremely poor. Due to its low price, the p235gh steel application materials are produced in many places. Therefore, some manufacturers choose when manufacturing low-cost drill rods.

The boiler steel pipe has excellent anti-oxidation and corrosion performance: the general steel pipe is easy to be corroded under high temperature and produces harmful substances, but the boiler steel pipe has no such worries. The high-precision material and wall thickness of the boiler steel pipe can effectively prevent the corrosion. Good tensile strength of p235gh steel application, boiler steel pipe: it can keep the original state well without affecting its quality after being heated and stretched.

30CrMo 35CrMo 25CrMo4 42CrMo4 and so on CrMo steels have good mechanical properties and hydrogen resistance at room temperature and high temperature. The main alloy elements in CrMo steel are molybdenum, chromium, vanadium, silicon, boron, etc. Molybdenum is a very important alloy element in the hot strength steel. It can significantly improve the hot strength of the CrMo steel, maintain sufficient strength at high temperature, refine the grains and prevent the overheating tendency of the CrMo steel, p235gh steel application.

p235gh steel application, P355GH plate mechanical properties: p355gh steel plate thickness/mm:> 60-100: tensile strength σb / MPa: 490-630; yield strength σx / MPa:> = 315 Impact absorption energy AKv / J:> = 34. Steel plate thickness / mm:> 100-150: tensile strength σb / MPa: 480-630,y ield strength σx / MPa:> = 295 Impact absorption energy AKv / J:> = 34. Chemical composition % (C:0.10-0.22, Si:<=03.60, Mn:1.00-1.70, Nb:<=0.010, Ti:<=0.03 S:<=0.030, P:<=0.025, Cr:<=0.30, Ni:<=0.30, Cu:<=0.30, Mo:<=0.10, V <=0.02)

As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another p235gh steel application magnificent projects.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
