Product Description

Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural parts.
In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchenware.

Stainless steel features: 1. Complete product specifications and diverse materials;
2. High dimensional accuracy, up to ±0.1mm;
3. Excellent surface quality and good brightness;
4. Strong corrosion resistance, tensile strength and fatigue resistance High strength;
5. Stable chemical composition, pure steel, low inclusion content;
6. Good packaging, preferential price;
7. Non-standard custom.

Surface Difference


No.1 (hot rolled): After hot rolling, annealing, pickling and dephosphorization. The surface of the treated steel plate is a dull surface, a bit rough.
Usage: chemical industry equipments.
No.2D: The surface is processed better than No.1, and it is also a dull surface. After cold rolling, annealing, dephosphorization, and finally rolling with a matt roll. 
Usage: petrochemical production equipment, auto parts, building materials, pipeline materials, etc.
No.2B: This is the most commonly used in construction applications. Except for the last light cold rolling with a polishing roll after annealing and dephosphorization, the other processes are the same as 2D, the surface is slightly shiny, and it can be polished.
Usage: After adopting the surface treatment method to improve the mechanical properties, it can meet almost all purposes.
BA:  After cold rolling, it is processed by bright annealing heat treatment process and modulated and rolled.
Usage: mostly used for home appliances, small mirrors, kitchen equipment and building materials that require high reflectivity.
No.4: First polish with coarse abrasive, and finally grind with 180 grit abrasive.
Usage: Mainly used for bathtubs, building interior and exterior decoration materials, food equipment, etc.
HL (hairline): Use grinding paper of appropriate granularity to make No.4 continuous grinding pattern
Usage: mostly used for building interior and exterior decoration materials and building sash, door, panel, etc.
8K: Continuously polish the stainless steel with a fine abrasive, and then polish it with a very fine polishing paste.
Usage: mirror surface processing, used for decoration materials, mirrors, etc.
