A500 Seamless Pipe Introduction

A500 Gr A, A500 Gr B, A500 Gr C, A500 Gr D,

A500 Gr A Seamless Pipe  structures generally consists of a converter or open hearth steel smelting, the main raw material for the molten iron plus scrap, steel, sulfur, phosphorus content is higher than high-quality carbon structural steel, general sulfur ≤0.050%, phosphorus ≤0.045%. Raw materials into steel by the other alloying elements such as chromium, nickel, copper, usually not more than 0.30%.

Stainless Steel Surface Finishes:

1. No 1 Finish : Used where Heat and corrsoion ressistance is required . Produced by annealing and resealing after hot rolling .

2. No 2D Finish : Dull Cold rolled finish . Used in deep drawn objects which are often polished after fabrication

3. NO 2 B Finish : Bright Cold Rolled Finish . Used in very deep drawn objects .

4. No 3 Finish : Polished finish obtained with abrasives

5. No 4 Finish : Used for kitchen ware , cooking utensils , restaurants and hotel kitchenware , cookware . Obtained with abrasives of 125 mesh and higher

6. NO 7 Finish : Architectural and Ornamental Finish

7. NO 8 Finish : Press plates , small mirrors and reflectors

8. Hairline finish : Ornamental plates , decorative items , name plates , elevators , doors in buildings
