ASTM A537 Steel Plate Class 1 Class 2 Class 3
FINISH AND SPECIFICATION
No.1

A rough, dull surface, which results from hot rolling to the specified thickness, followed by annealing and descaling.

Range (mm)10001219125015001524
3.0~6.0ΔΔΔΔΔ
8.0~100.0 Δ  Δ
2D

A dull finish which results from cold rolling followed by annealing and descaling, and may perhaps gets a final light roll pass through unpolished rolls. A 2D finish is used where appearance is not a concern.

2B
(Mill Finish)

A bright, cold-rolled finish resulting in the same manner as 2D finish, except that the annealed and descaled sheet received a final light roll pass through polished rolls. This is the general-purpose cold-rolled finish that can be used as is, or a preliminary step to polishing

BA
(Bright Anneal)

The bright annealed mill surface is obtained by annealing the material under an atmosphere, so that scale is not produced on the surface.

Brushed Finish
(No.3/No.4/No.5/No.6)

This is a ground unidirectional finish obtained with 150/180/240/320 grit abrasive, which is characterized by parallel brushing lines, it is also known as Satin.

Scotch Brite

It's a semi-dull finish with uniform grain, which is obtained using finer abrasives than No.4/NO.5/NO.6. This finish has smooth, soft and exquisite grains which has a low level of reflectivity and unidirectional texture.

Hairline

Seemingly endless polishing lines extend uniformly along with the length of the coil give the hairline. It's a well-defined directional finish with long-grain and fine-line.

Super Mirror
(No.8)

This is a polished finish having a high degree of reflectiveness which can be done on all the grades of stainless steel. It is produced by progressively using finer abrasives and finally finishing with extremely fine buffing compounds. The final surface is blemish free with a high degree of image clarity.

Vibration

Vibration is a multi-directional finish. It is also known by the names Non-Directional Satin and Angel Hair. Vibration has a uniform texture with random, multi-directional grit lines.

CD Overlay

CD Overlay is a patterned polished steel finish that is applied mechanically to the surface of stainless steel sheets. These stainless polished steel finishes can be created with various visual effects, which are designed for architectural and other applications.

Bead Blast

This finish results in a non-directional textured surface with a soft satin reflection and low reflectivity.This finish has an aesthetic appeal and enhances the surface properties of stainless steel.

Etched Finish

Etched patterns are created by selectively applying a protective acid resistant film to a highly polished surface and acid etching the unprotected areas. The etching removes a thin layer of stainless steel, changes the color to a dull silver gray, and roughens the surface. Etched finished made an attractive surface on the metal, which is applied on architectural and other applications.

Embossed Finish

Embossed finish is a stainless steel finish that is uniformly textured. There are two main types of Embossed Finish: 1 sided pattern, where the reverse side is paint; another one is 2 sided patterns where the pattern is imprinted through to reverse side.

PVD Coating

Physical Vapor Deposition (PVD) is a process to produce a metal vapor (titanium, chromium and aluminum) that can be deposited on electrically conductive materials as a thin highly adhered pure metal or alloy coating. The process is carried out in a vacuum chamber at vacuum using a cathodic arc source. A wide variety of colors can be achieved by adding other gases during the deposition.

ASTM A537 Steel Plate Class 1 Class 2 Class 3

Product Scope:

ASTM A537 of all grades, ASTM A537 specification covers the standard for heat-treated carbon manganese-silicon steel plates intended for fusion welded pressure vessels and storage tank. It is a kind of low alloy steel that covers 3 grades (Class 1, Class 2, Class 3) , steel plate of these grades are used when yield and tensile strength of ASTM A516 can not meet the requirements of pressure services like boiler and pressure vessels in oil, gas, petroleum industries.

ASTM A537 class1 steel plate typical applications are API 650 and API 620 storage tanks, pressure vessels designed for moderate and lower-temperature service, requiring excellent notch toughness. Class 1 steel is finished as Normalized and Class 2 is finished as Quenched & Tempered plates. A537 Class 1 steel plate shows good cold forming performance, for welding, special consumables and welding methods are needed for avoiding harmful effects of metal structure.
