ASTMA335 steel pipe of grades P23,P91, P92, P122, and P911 shall be reheated and furnished in the full-annealed, isothermal annealed,or normalized and tempered condition. If furnished in the normalized and tempered condition, the minimum tempering temperature for Grades P5, P5b, P9, P21, A572 Gr 42 CS steel carbon plate product and P22 shall be1250°F [675°C], the minimum tempering temperature for Grades P1, P2, P11, P12, and P 15 shall be 1200°F [650°C].
The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing A572 Gr 42 CS steel carbon plate high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.
Medium and thick steel plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on. However, each project has different requirements for plate size. How to cut A572 Gr 42 CS steel carbon plate, medium and thick steel plates? There are many ways, for example, flame cutting, laser cutting, wire cutting, plasma cutting, ultra-high pressure water cutting and so on.
A572 Gr 42 CS steel carbon plate, Q345C steel plate is a kind of weldable low carbon engineering structure material, which is generally produced by continuous rolling mill. The carbon content of Q345C steel plate is less than 0.25%. The yield strength σ0.2 of Q345C steel plate is 300- 800MPa and the yield ratio is 0.65- 0.95. Q345C steel plate has excellent low temperature toughness. That is mainly owe to the solid solution of alloy elements (Mn, Si, Al, Cr, etc.), grain refinement (Nb, V, Ti, etc.), precipitation hardening (Nb, V, Ti, etc.), phase transformation strengthening (Mn, Si, Mo, etc.), and controlled rolling and controlled cooling, etc. new technologies.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
