The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the A572 grade 42 ms steel coil and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.
In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.
The JIS G3106 A572 grade 42 ms steel coil specification is a hot-rolled carbon steel plate for welded structures. The A572 grade 42 ms steel coil steel grades include: SM400A/B/C, SM490A/B/C, SM490YA/YB, SM520B/C, SM570.
