304 Stainless Steel Rod Round Bar

304 stainless steel smooth round refers to the smooth surface, which is processed by finishing rolling, peeling or cold drawing polishing; it is often used in various chemical, food, textile and other mechanical equipment and certain decorative purposes. The so-called 304 stainless steel black round or 304 stainless steel rod (black rod) refers to the round steel whose surface is black and rough, directly hot-rolled, forged, or annealed without processing the oxide layer on the surface.

304: 18-8 stainless steel, the reference GB grade is 0Cr18Ni9; American standard implementation standard: ASTM A276.

GB: C≤0.07; Si≤1.0; Mn≤2.0; P≤0.045; S≤0.03; Ni: 8.0-11.0; Cr: 17.0-19.0

ASTM: C≤0.08; Si≤1.0; Mn≤2.0; P≤0.045; S≤0.03; Ni:8.0-11.0; Cr:18.0-20.0

304 stainless steel is the most widely used chromium-nickel stainless steel, which has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. [1]

According to the production process, 304 stainless steel round steel is divided into three types: hot rolling, forging and cold drawing. The specification of hot-rolled 304 stainless steel round bar is 5.5-130 mm. Among them: 5.5-25mm small 304 stainless steel round steel is mostly supplied in straight strips, often used as steel bars, bolts and various mechanical parts; or directly in the round state, as semi-finished products for subsequent reprocessing. 304 stainless steel round steel larger than 25 mm is mainly used to manufacture mechanical parts or perforate seamless steel tube billets.
