Product Description

Cold Drawn 304L 316L Stainless Steel Square Bar Rod Supplier Cold drawn stainless steel square bar is a type of stainless steel bar that is produced by cold drawing process. This process involves pulling the stainless steel through a die to shape it into a square cross-section. High dimensional accuracy: Cold drawing process ensures precise dimensions and tight tolerances, resulting in a bar with consistent size and shape. Smooth surface finish: The cold drawing process eliminates surface imperfections and irregularities, resulting in a smooth and polished surface finish. Improved mechanical properties: Cold drawn stainless steel square bar possesses enhanced mechanical properties compared to hot rolled bars. It has higher tensile strength, yield strength, and hardness. Increased corrosion resistance: Stainless steel is inherently corrosion resistant, and the cold drawing process further enhances its resistance to corrosion. This makes cold drawn stainless steel square bar suitable for various applications where corrosion resistance is crucial. Versatility: Cold drawn stainless steel square bar is available in a wide range of grades, including austenitic, martensitic, ferritic, and duplex stainless steels. This ensures its suitability for various industrial applications, such as construction, automotive, aerospace, and more. Good machinability: Cold drawn stainless steel square bar is easy to machine and work with. It can be easily cut, drilled, welded, and formed into desired shapes. Cost-effective: Although the cold drawing process adds an extra step in the production process, cold drawn stainless steel square bar is often more cost-effective compared to other manufacturing methods, such as hot rolling. Specification: Standard: ASTM, AISI, DIN, EN, GB, JIS Dimensions: 1) Hot rolled black bar: (5*5-400*400)x6000mm or according to your requests. 2) Acid square bar: (5*5-400*400)x6000mm or according to your requests. 3) Cold drawn square bar: (1*1-20*20)x6000mm or according to your requests. 4) Polishing square bar: (5*5-400*400)x6000mm or according to your requests.

Before You Order

How to Choose & How to Handle

Five decisions cover most orders. If any of them is unclear, send us the drawing or the application and we will narrow it down.

How to choose the right grade and size

1Grade. 304 for general fabrication, 316L for marine, chemical or coastal service, 201 for cost-sensitive indoor work, 430 for appliances and trim. Grade comparison →
2Thickness. 0.3–200 mm. Cold rolled covers 0.3–3.0 mm at ±0.02 mm; above that we supply hot rolled and pickled.
3Surface. 2B is the default for fabrication, BA for bright decorative work, No.4 for brushed visible faces, HL for hairline, 8K for mirror.
4Size. Mill standards are 1219×2438 and 1500×3000 mm. Anything else is cut to size, with no extra lead time on stock items.
5Documents. Every shipment carries EN 10204 3.1 MTC. Ask for SGS / BV / Intertek pre-shipment inspection if your project requires it.

Handling, cutting and storage

Store indoors on timber battens, never directly on concrete. Keep away from chlorides, acids and salt spray.
Cut clean. Plasma, laser or waterjet. Never use tooling that has cut carbon steel without cleaning it first — iron contamination rusts.
Weld matched. 308L filler for 304, 316L for 316L. Keep interpass temperature low and passivate the weld zone afterwards.
Protect faces. Visible surfaces ship with PVC film. Remove it within six months and never leave it in direct sun.
Lift, don't drag. Use suction lifters or a spreader beam. Dragging scores the finish and edges.
Check on arrival. Photograph packing before unloading. Report transit damage within 7 days so we can claim with the carrier.
