Silver Color Strong And Durable Rust Proof 10s20 Bright Steel Round Bars

Product Description

Manufacturer a : Dongguan Songshun Mould Steel Country of origin: china Attributes: - heavy duty - corrosion-resistant Additional information: 10S20 (1.0726) is an S-P composite low-carbon free-cutting steel, which has the highest phosphorus content among the existing free-cutting steels. The mechanical properties of 10S20 (1.0726) steel have obvious anisotropy. The longitudinal mechanical properties of cold-drawn steel are close to those of cold-drawn No.15 steel. It often replaces No. 15 steel to manufacture various parts that do not require high mechanical properties, such as bolts and nuts. , pins, shafts, pipe joints, and spark plug jackets, etc. Chemical composition: - Carbon C: 0.07i 0.13 - Silicon Si: a 0.40 - Manganese Mn: 0.70i 1.10 - Sulfur S: 0.15i 0.25 - Phosphorus P: a 0.06 Mechanical properties: - Tensile strength I b (MPa): (hot-rolled) 390-540; (cold-drawn) steel thickness or diameter 8-20: 530-755; >20-30: 510-735; >30: 490-685 - Elongation I'5 (%): (hot-rolling)a Y22; (cold rolling)a Y7.0 - Area shrinkage I (%): (hot-rolling)a Y36 - Hardness: (hot rolled)a 170HB; (cold drawn) 152i 217HB
