The production process of SA572 Gr 65 carbon steel plate sheet

The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.

Although both HSLA steel plate and carbon steel plate belong to carbon structure and low alloy structure steel, there are some differences. First of all, SA572 Gr 65 carbon steel plate sheet, HSLA steel plate and carbon steel plate differ in strength, hardness and use. In terms of strength, the strength of HSLA steel plate is higher than carbon steel plate. In terms of hardness, the hardness of HSLA steel plate is also higher than that of carbon steel plate. And in the scope of use, the advantages of HSLA steel plate are more prominent, so the scope of HSLA steel plate use is more extensive than that of carbon steel plate.

The purpose of SA572 Gr 65 carbon steel plate sheet quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of SA572 Gr 65 carbon steel plate sheet. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

SA572 Gr 65 carbon steel plate sheet, Q690 steel is low alloy high strength steel. It belongs to the Chinese GB standard steel. Q690 steel is named after its yield strength value. Q is the abbreviation of yield strength, that is, the yield strength of Q690 steel is 690 MPa. Chemical composition of Q690 steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 1.00, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. The mechanical properties of Q690 steel are: yield strength ≥ 690 MPa, tensile strength 730-940 MPa, elongation after fracture ≥ 14%, impact energy 31J.

The company's logistics team adheres to the development concept of “gathering advantages, providing superior services, creating value, and leading the market”, and tightly focuses on the strategic positioning of “developing large-scale steel logistics and building large-scale steel supermarkets”. Facing the whole country and integrating into the world to build an "one center, one network" international circulation system. Through the development of 5-10 years, it is expected to form a modern steel industry with annual operating income exceeding 2.5 billion yuan.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our SA572 Gr 65 carbon steel plate sheet products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
