A high-strength, elastic and high-cutting performance spring steel raw material, characterized by the above-mentioned spring steel raw material with a net weight ratio of 0.48% ~ 0.55% C, 0.17% ~ 0.37% Si, 0.70% ~ 1.00% Mn, 0.8% ~ 1.10% Cr, 0.001% ~ 0.004% B, ≤ 0.35% Ni, ≤ 0.25% Cu, ≤ 0.03% P, ≤ 0.03% S, and the others are Fe.
This hemiplegic steel is a high-strength, elastic and high-cutting spring steel raw material with strong elasticity and high cutting performance with 50CrVA and very high cutting performance with very high cutting performance and high cutting performance at a very high price.
In order to make a good filling for the raw materials of GB1222-92 spring steel at this stage. It is suitable for the production of steel raw materials for the production of elastic elements with large cross-section and high strength elasticity, and is very suitable for the production of steel raw materials for the production of leaf springs with a thickness of ≥ 20mm and a ≤ of 36mm. Compared with the current technology, this product has many advantages such as the development of the composition economy, wide application coverage, high elasticity and good cutting performance.
