What is the difference between RINA grade A floating dock steel and ST37-2 material

After heat treatment and cold drawing hardening, 65Mn steel has higher strength, certain toughness and plasticity; under the same surface state and complete hardening, the fatigue limit is equivalent to that of alloy springs. However, due to poor hardenability, it is mainly used for springs of RINA grade A floating dock steel smaller sizes, such as pressure regulating springs, force measuring springs, round and square spiral springs on general machinery or drawn into steel wires as springs on small machinery.

20# steel is carbon steel with carbon content of about 0.20%. It belongs to low carbon steel with high quality. The equivalent material of 20# steel is S20C. 20# steel has low strength and hardness, good plasticity and toughness, good carburizing effect and good weldability. 20# steel is often used to make pressure parts (such as gasket, chain piece), carburizing parts (gear, CAM), welding parts, plastic mold, etc.

RINA grade A floating dock steel, Composite wear-resistant steel plate can be formed by laser processing, but in this process, there are still many factors that will affect the laser forming effect of composite wear-resistant plate, including the input laser energy, the geometric size of bending parts and the properties of materials. There is a close relationship between them. The influence of thermal physical properties and mechanical properties of composite wear-resistant steel plate on laser bending is complex.
