430F Stainless Round Bar Stock

Due to the presence of large amounts of chromium in the 4 to 30% range, 430F stainless round bar stock.

The perfect 430F stainless round bar stock for your business

Due to the presence of large amounts of chromium in the 4 to 30% range, 430F stainless round bar stock. This material is known as precipitation-hardened steel because of its combination of martensitic and austenitic steel. The chemical composition of 430F stainless bar stock is as follows: iron 81%, chromium 16%, manganese ≤ 1.25. silicon ≤ 1, molybdenum ≤ 0.60, sulfur ≥ 0.15, carbon ≤  0.12, and potassium ≤  0.060. A few other things you may want to consider looking into is the physical properties and mechanical properties that 430F stainless bar stock has: For its physical properties the steel has a density of 7.80 g/cm3, and a melting point of  1482C; 430F’s mechanical properties are as follows: tensile strength ultimate 550MPa, modulus of elasticity 200GPa, Poisson’s ratio 0.27 – 0.30, elongation at break (in 50 mm) 25%, hardness Brinell 170, hardness Knoop (which is converted from Brinell hardness) 189, hardness Rockwell B (which is converted from Brinell hardness) 86, and hardness Vickers (which is converted from Brinell hardness) at 178.
