What is V4A stainless steel?
V4A stainless steel is a non-magnetic, heat-treatable steel that can also be cold-formed. It is easy to shape and polish, and can be welded using standard methods such as TIG and MAG. The addition of 2-2.5% molybdenum gives it excellent resistance to corrosion in saltwater and chloride-containing environments, making it ideal for marine and chemical applications.
What is the material equivalent to V4A?
The material equivalent to V4A is primarily AISI 316/316L stainless steel, also known by the material number 1.4404 (316L) or 1.4401 (316). These grades are known for their high corrosion and acid resistance, which comes from the addition of molybdenum and increased chromium and nickel content.
Common grades: V4A is associated with grades like 1.4401, 1.4404, and 1.4571, and is equivalent to the AISI 316L standard.
Is A4 stainless steel the same as 316L?
Yes, V4A is a German designation for stainless steel that is commonly synonymous with 316L stainless steel, which is part of the larger AISI 316 family. Both are high-quality, corrosion-resistant chromium-nickel-molybdenum steels used for demanding applications.

What is the equivalent casting material for 316L?
The equivalent casting material for 316L stainless steel is designated as CF3M. This material is clearly defined in ASTM standards such as A351, A743, and A744.
What is the difference between V2A and V4A stainless steel?
V4A stainless steel has significantly better corrosion resistance than V2A due to the addition of molybdenum, making it the preferred choice for harsh environments like coastal areas or near saltwater. V2A stainless steel (like AISI 304) is sufficient for general indoor and less-demanding applications, offering good durability and versatility at a lower cost.
V2A vs 304 stainless steel
V2A and 304 stainless steel are the same material, but with different naming conventions. V2A is the German designation for the austenitic stainless steel that is widely known in American standards as 304 or AISI 304. It is a popular, versatile alloy known for its good corrosion resistance, mechanical properties, and wide use in industries like food, chemical, and manufacturing.
