AL 201LN™ is a special composition of Type 201 specifically for sub-zero temperature service as welded tanks and vessels. This alloy has replaced the familiar 300 series stainless such as type 301 or type 304 in many applications based upon technical equivalency and economic considerations. AL 201LN alloy is a natural choice for use at temperatures down to -320°F. The alloy is suited for many ambient temperature structural applications, such as railroad freight cars, truck trailers, coal handling and other bulk transport equipment where there is need for a good combination of corrosion resistance, strength, toughness and ease of fabrication.
