S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. EN 10083-3 38MnB5 alloy steel grade, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265. Tensile strength: 450-680MPa.
Sprin steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. EN 10083-3 38MnB5 alloy steel grade, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. The smelting of EN 10083-3 38MnB5 alloy steel grade, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to guarantee high purity. The content of sulfur, phosphorus, oxygen and nitrogen of spring steel should be low, and the uniformity and stability of spring steel should be good.
The influence of thermal physical properties and mechanical properties of composite wear-resistant steel plate on laser bending is complex, which mainly involves the thermal expansion coefficient, specific heat capacity coefficient, thermal diffusion coefficient, yield limit, elastic modulus and hardening index. Under the same process conditions, the greater the specific heat and thermal conductivity of the composite EN 10083-3 38MnB5 alloy steel grade, wear-resistant steel plate, the less obvious the temperature gradient in the forming process, and the smaller the bending angle produced.
