Alloy steel BP300 steel use for strong box to manufacture steel pipes

The company adheres to the people-oriented concept and takes "learning, sharing, gratitude, integrity, respect and responsibility" as the enterprise values. Advanced equipment, scientific standardized management, strict quality assurance system and high-quality team are the core competitiveness of the company. The company will continue to provide customers with BP300 steel use for strong box high-quality, timely and perfect steel products and services under the guidance of the mission of "striving for perfection to meet customer needs".

Pickling steel sheet grades: SPHC, SPHD, SPCE, SS400, St37-2, St52-3, JSH270C, JSH440W, S315MC, S355MC, S420MC, S460MC, S500MC, S550MC, S600MC, S700MC, SAPH310, SAPH370, SAPH400, SAPH440, BP300 steel use for strong box, SAE1008, SAE1022, QStE340TM automotive structural steel, QStE380TM, QStE420TM, QStE460TM, QStE500TM, QStE550TM, B330CL, B380CL, B420CL, B510LS20C, S35C, S45C, DP600, ZQS500L.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This BP300 steel use for strong box alloy steel BP300 steel use for strong box still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, BP300 steel use for strong box.

BP300 steel use for strong box, API 5L X52 steel with the thickness range is 1.2-40mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. API 5L X52 steel’s mechanical properties is the yield strength 300MPa, and the tensile strength 460MPa. To be specified in details: Maximum content for C≤0.28%, Mn≤1.4%, P≤0.030%, S is 0.030%, V+Nb+Ti≤0.15%, Copper maximum is 0.50%, nickel maximum 0.50%, chromium 0.50%, Molybdenum 0.15%.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate BP300 steel use for strong box EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
