Stainless steel is an iron-based alloy containing chromium, which helps improve corrosion resistance. Elements such as nickel, molybdenum and carbon influence the strength, formability and performance of different grades.
Metalloy Steel deals in a range of stainless steel grades, including SS 304, SS 316, 17-4 PH, Duplex 2205 and Super Duplex 2507. These grades are available across selected product forms to meet varied industrial and engineering requirements.
Metalloy Steel offers stainless steel products across several product categories. Explore the existing product pages to review the relevant grade and product information.

Material verification confirms that supplied products meet the specified grade and order requirements. Testing and documentation depend on the applicable standards and agreed supply conditions. Verification may include:
Documentation identifying the material and reporting applicable test results, where supplied.
Review of the reported chemical composition against the applicable material specification.
Review of relevant proof stress, tensile strength, elongation or hardness results where required.
Material identification testing where specified and available.
Independent inspection where agreed for the order.
