Stainless steel is an iron-based alloy containing at least 10.5% chromium. Chromium forms a protective chromium oxide layer on the surface, preventing rust from penetrating the iron.Stainless steel can be classified into\u00a0duplex structure classes<\/strong>\u00a0y\u00a0single heat-treatment classes<\/strong>, which fall under the same general category for most types. The numbering system divides stainless steel into five categories: martensitic, austenitic, ferritic, duplex, and precipitation-hardening<\/strong>.In this article, we will examine the different types of stainless steel.<\/p>\n

Acero inoxidable martens\u00edtico<\/strong><\/span><\/h3>\n

Martensitic stainless steels are a class of stainless steel whose properties can be adjusted through heat treatment (quenching, tempering). These steels primarily consist of iron and carbon (up to ~2 wt.%), with chromium content ranging from 10.5% to 18% and carbon content not exceeding 1.2%.<\/p>\n

For\u00a0Grade 403<\/strong>, no additional parameters are specified\u2014it is a basic martensitic stainless steel. Other martensitic steels (e.g., 403, 410, and the 400 series) are considered hardenable.<\/p>\n
