Product Description
Spring steel plate has excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit, yield ratio), elastic reduction performance (i.e. anti elastic decline performance, also known as anti relaxation performance), fatigue performance, hardenability, physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, corrosion resistance, etc.). In order to meet the above performance requirements, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), accurate shape and size.
A commonly used model is 65Mn. Let me introduce its chemical properties

Application
The strength, hardness, elasticity and hardenability of 65Mn steel plate are higher than those of No. 65 steel. It has the tendency of overheat sensitivity and temper brittleness, and water quenching has the tendency to form cracks. The machinability of annealed state is acceptable, the cold deformation plasticity is low, and the weldability is poor. Medium load leaf spring, coil spring with diameter up to 7-20 mm and spring washer, spring ring. High wear resistant parts, such as grinder spindle, spring clip, precision machine tool screw, cutter, sleeve ring on spiral roller bearing, rail, etc.
Packing & Delivery
1. Standard seaworthy export packing, wooden pallets with plastics protection .
2. 20' container load 25tons,length ≤5.8
40' container load 27tons,length ≤11.8
3. The other packing can be made based on the customer requirement;
Normally, we have four layers of packing: wooden pallets, hardboard, Kraft paper and plastic.
