ASTM Stainless Steel Rebar Standard Specification
Salit Specialty Rebar is a leading supplier of cut and pre-assembled stainless steel rebar and mesh.
The ASTM A955/A955M Standard Specification for Deformed and Plain Stainless-Steel Bars for Concrete Reinforcement is the main Standard for stainless steel rebar in the USA and Canada. The dimensional bar profiles and grade structure (strengths) follow their respective carbon steel standards.
Where this Standard diverges from carbon steel standards is the informational content relating to the numerous types of stainless bar that meet the standard, specific chemistry details, reference to corrosion resistance requirements, specification of magnetic permeability requirements, surface finish and pickling instructions, and most importantly, a set of mandatory corrosion tests. This is manufacturer specific and not alloy designation specific.
Stainless Steel Rebar Mechanical Properties
|Grade 60 ||Grade 75 |
|Tensile strength, min. psi [MPa]||90,000 ||100,000 |
|Yield strength, min. psi [MPa] *||60,000 ||75,000 |
|Elongation in 8 in. [200 mm], min. % for all bar designation numbers||20||20|
*Yield is measured by the offset method (0.2% offset) as described in Test Methods and Definitions A370.
