Description
Gnee Steel (Tianjin) Co., Ltd. is one of the most professional manufacturers and suppliers of 304 stainless steel cold rolled bar in China. With abundant experience, we warmly welcome you to wholesale customized 304 stainless steel cold rolled bar from our factory. For price consultation, contact us.
304 stainless steel cold rolled bar (UNS S30400) is an office austenitic stainless steel bar. The surface finish (Ra≤0.8μm) and mechanical properties are improved through the cold rolling process. It is widely used in construction, machinery manufacturing, food and medical fields.
304 stainless steel bar contains 18% Cr and 8% Ni, is resistant to acid, alkali and atmospheric corrosion, suitable for outdoor and humid environments, tensile strength ≥520 MPa, yield strength ≥205 MPa, high pressure resistance, dimensional tolerance ±0.05mm, smooth surface without oxidation, reducing subsequent processing costs.

FAQ
Q: How to distinguish 304 cold drawn rod from 316 cold drawn rod?
A: Spectral detection: 316 contains 2-3% molybdenum, 304 does not.
Salt spray test: 316 has a corrosion resistance time of more than 3 times that of 304 in 30,000ppm Cl⁻.
Price: The cost of 316 cold drawn rod is about 50-80% higher than that of 304.
Q: How to store to prevent rust?
A: Store in a dry and ventilated place, avoid contact with water, salt spray or acidic gas.
Apply anti-rust oil on the surface or use moisture-proof packaging (suitable for long-term storage).
Different materials should be stored separately to prevent electrochemical corrosion (such as mixing with carbon steel).
