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 S235J0W cold rolled steel strips 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.

S235J0W cold rolled steel strips, Q215A steel belongs to carbon structural steel. Q215A steel does not contain specially added alloy elements. S235J0W cold rolled steel strips, Q215A steel is mainly used in construction and engineering structures. Chemical composition of Q215A steel: C: ≤ 0.15, Si: ≤ 0.30, Mn: ≤ 1.20, P ≤: 0.045, S ≤: 0.050. Q215A steel has low carbon and manganese content. Q215A steel strength is slightly higher than Q195 steel strength. S235J0W cold rolled steel strips, Q215A steel has good plasticity, good toughness, weldability and process performance. Q215A steel is mainly used in plant building, bridge components, tower, derrick and vehicle and ship manufacturing components.

Punchability refers to the performance of metal without cracks and other defects after stamping deformation. Many steel products are manufactured through a stamping process. In order to ensure the quality of the products and the smooth progress of the process, the S235J0W cold rolled steel strips, steel plates and strips used for stamping must have qualified stamping performance.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
