Glorysteelwork is the manufcture of hot rolled spring steel flat bar in china, we could offer different grades square bar with high quality.

Spring steel refers to steel that is specifically used to make springs and elastic components due to the elasticity in the quenched and tempered state. The elasticity of steel depends on its elastically deformation ability, that is, within the specified range, the elastically deformation ability makes it withstand certain load and no permanent deformation occur after the load is removed. Spring steel should have excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit, yield ratio), anti-ballistic properties (ie, anti-elasticity, also known as anti-relaxation), fatigue properties, hardenability physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, corrosion resistance, etc.). In order to meet above performance requirements, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), precise shape and size.
