Main properties and application range of S355MC steel

S355MC steel is a new type of carbon steel with high strength, high plasticity and welding properties. It has good low temperature toughness and can be processed by various welding processes. S355MC steel application: In the high strength structural steel plate, the strength grade is high. Components used in the manufacture of Bridges, vehicles, mechanical structures and ships. Used for the production of strong impact and little temperature change components, such as rolling mill frame, lifting equipment, boiler parts and various mechanical parts.

S355MC steel chemical composition and mechanical properties  
Product name: S355MC
Material grade: 40 Cr
Material grade: C (alloy structural steel)
Scope of application: It is generally used to manufacture mechanical parts that withstand impact and have little temperature change, such as Bridges and automobile parts.
Mechanical properties: The steel has good low temperature toughness, low temperature impact toughness of 31.8J/cm2, 10~15 times higher than ordinary low carbon steel plate. Tensile strength σb≥930 MPa, yield strength of 540 MPa above, can be welded.

Main Characteristics and application scope of S355MC Steel:
The main characteristic of S355MC steel is its high strength, while its high plasticity, toughness and weldability can be processed into the desired shape, size or performance through various welding processes.
1. Has high low temperature toughness, can withstand the impact load in the temperature range of -196℃~600℃ and small size, has good weldability, can carry out a variety of welding process.
2. At low temperature, S355MC steel has higher strength than low alloy structural steel and carbon structural steel, especially it has better cold deformation performance.
3. Easy to process or roll molding.
4. Main uses: Used for manufacturing large impact load and temperature changes in the occasion of little working pressure, high strength requirements but also have certain requirements for toughness of structural parts such as boilers and containers, automotive drive shaft and large mechanical parts.
Remarks: 1) S355MC steel should be selected when the impact load is not large or the temperature change is not large.
