Product Introduction

Hardened And Tempered Steel Sae 1055 Spring Steel. It is also known as hardened and tempered steel due to the heat treatment process it undergoes to achieve its desired properties.

The hardening and tempering process involves first heating the steel to a high temperature to make it austenitic (able to dissolve carbon). The steel is then quenched (rapidly cooled) to transform the austenite into martensite, a very hard and brittle phase of steel. To improve its toughness and strength, the steel is then tempered by heating it at a lower temperature to allow some of the martensite to transform into a tougher and more ductile phase of steel.

The resulting sae 1055 spring steel has a high strength-to-weight ratio, high tensile strength, good fatigue resistance, and excellent spring properties. It is used in many applications, such as automotive springs, railway springs, safety valve springs, and clutch springs, among others. It is also used in the production of cutting tools, knives, and swords, due to its hardness and toughness.

Physical properties: The hardness level of spring steel is HRC48-54, the tensile strength is 655 MPa, the yield strength is 585 MPa, and the elongation is 12%.
Chemical composition: The chemical composition of the steel should meet the following requirements: carbon (C) 0.50-0.60%, phosphorus (P) ≤ 0.035%, sulfur (S) ≤ 0.050%, manganese (Mn) 0.60-0.90%.
Process: After quenching and tempering treatment, to improve the strength and toughness of the steel to adapt to the flexure and resilience requirements of various springs.
Use: Widely used in automobile, machinery, furniture, construction and agricultural equipment and other industries, for the production of spring, steel wire, blade, wrench and other industrial parts.
Supply status: The product specifications can be supplied, including plate, bar, wire and pipe and other shapes and sizes, can be cut, cutting, drilling, drilling and other processing.
