What is minimum yield strength of weathering steel SMA490BP?

In recent years, in line with the development trend of iron and weathering steel SMA490BP steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which weathering steel SMA490BP are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

ASTM A36 h beam is a common wide flange beam used in construction and machinery for its medium strength. Low carbon weathering steel SMA490BP content makes it easy to be welded, machined as well as formed. Therefore, it is often employed by light applications where strength need is not so important.

Pipeline steel is a kind of steel specially used for transporting natural gas and petroleum with special requirements. Why do oil and gas pipelines use pipeline steel as the transportation pipeline? Because pipeline steel has the following characteristics. First, the pipeline steel is strong, and it is not easy to break. If it breaks during transportation, the consequences are unimaginable. Second, the weathering steel SMA490BP, pipeline steel is durable. Pipeline steel is buried deep underground for a long time and has good corrosion resistance. Third, the pipeline steel is resistant to high temperature and will not deform under high temperature.

The microstructure of the quenched and tempered alloy steel, weathering steel SMA490BP 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.

"High strength low alloy steel plate pecifications: weathering steel SMA490BP, A516 Grade 60 plates and sheets are producted with thickness up to 200mm [8 inch].A516 Grade 60/70 Dual Certified HIC NACE TM0284 Plates Hydrogen Induced Cracking;Hot Rolled Steel ASTM A516 Grade 60 Dual Certified HIC Tested Plates in accordance with Nace Test Method, ASTM A516 70 HIC Tested (Hydrogen Induced);Tested Fine Grained Pressure Vessel Steel Plates For Sour Gas Service."

The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products weathering steel SMA490BP and won a good reputation. We can offer various kinds of steel materials in GB, ASME, ASTM, JIS, DIN, EN, API standards and specifications.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
