Physical and chemical properties:

Physical properties:

Density: about 7.93g/cm ³. – Melting point: 1398~ 1454 ℃. – Specific heat capacity (0~ 100 ℃): 0.50KJ · kg-1K-1. – Thermal conductivity (100 ℃): 16.3W · m-1 · K-1. – Linear expansion coefficient (0~ 100 ℃): 17.2 × 10-6 · K-1. – Resistivity (20 ℃): 0.73 × 10-6 Ω · m2/m. – Hardness: ≤ 217HBS.

Chemical properties:

Its main chemical composition (%) is: carbon (C) ≤ 0.08, silicon (Si) ≤ 1.00, manganese (Mn) ≤ 2.00, phosphorus (P) ≤ 0.040, sulfur (S) ≤ 0.030, chromium (Cr) 17.0~ 19.0, nickel (Ni) 8.0~ 11.0, copper (Cu) 3.0~ 4.0. S30430 stainless steel belongs to austenitic stainless steel. Compared with 304 stainless steel, it can obtain greater cold deformation under the action of smaller deformation force, and is more suitable for cold heading, cold extrusion as fasteners or deep drawing, stretching and other purposes. It has good corrosion resistance, processability and weldability, and is commonly used in chemical equipment, mechanical parts used under corrosion-resistant conditions, bolts and nuts, pressure vessels and other fields. The specific nature may vary due to differences in production processes and quality control.
