ASME SA572 carbon steel plate sheet for machinery manufacturing

Austenitic stainless steel has good plasticity and low strength, but its corrosion resistance is the best among the stainless steels. ASME SA572 carbon steel plate sheet, Austenitic stainless steel is suitable for the occasions where the mechanical properties are not required to be very high, such as chemical plants, chemical fertilizer plants, sulfuric acid and hydrochloric acid manufacturers, etc. Of course, austenitic stainless steel can also be used in submarine and other military industries.

At the same time of doing well in ASME SA572 carbon steel plate sheet production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the ASME SA572 carbon steel plate sheet technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for ASME SA572 carbon steel plate sheet pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common ASME SA572 carbon steel plate sheet carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.

The microstructure of the quenched and tempered alloy steel, ASME SA572 carbon steel plate sheet after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world.
