What is ASTM A666 316 cold-worked stainless steel sheet?
ASTM A666 316 cold-worked stainless steel sheet is a high-strength, corrosion-resistant austenitic stainless steel that is cold-worked rather than annealed, conforming to the ASTM A666 standard – "Standard Specification for Annealed or Cold-Worked Austenitic Stainless Steel Sheets, Strips, Plates and Flats". The controlled cold-working process enhances its mechanical strength while maintaining its excellent corrosion resistance.
ASTM A666 316 cold-worked stainless steel sheet is ideal for applications requiring high durability and surface finish, such as chemical processing, marine equipment, heat exchangers, and structural components.

What are the surface treatment options for A666 316 rolled steel sheets?
GNEE offers a variety of surface treatments upon request. A666 Gr 316 steel strip is available with standard polishing, bright annealing, and mirror polishing. Sandblasting and brushed finishes are also available. ASTM A666 316 perforated steel sheets with spaced-distribution holes are commonly used in applications such as filtration, construction, and food processing.
What is the main difference between annealed and cold-worked 316 stainless steel?
Annealed 316 offers maximum ductility and corrosion resistance, while cold-worked 316 provides higher mechanical strength but slightly reduced formability.
Can ASTM A666 Type 316 Cold-Worked Sheets be welded?
Yes, but post-weld annealing is recommended to restore corrosion resistance and relieve residual stress.
Is cold-worked 316 suitable for seawater environments?
Yes. Due to its molybdenum content, it resists pitting and crevice corrosion even in brackish or marine conditions, making it a true marine-grade alloy.
What is the hardness of ASTM A666 Type 316 full hard sheet?
Typically around 35–38 HRC, providing exceptional wear resistance.
ASTM A666 Type 316 Cold-Worked Sheet price per kg
| Region | Price Range (USD/kg) |
|---|---|
| Asia (China, India) | $3.8 – $4.5 |
| Europe | $4.6 – $5.2 |
| North America | $4.4 – $5.0 |
Prices fluctuate based on thickness, hardness level, finish, and quantity ordered. Bulk procurement and direct mill supply can reduce cost by 8–12%.Email: info@gneestainless.com
