2Cr13 use
Introduction
The main purpose of stainless steel is for corrosion resistance as its corrosion resistance is due to chromium. Chromium oxide layer is formed when that oxide layer oxidizes by reacting it with oxygen. This reaction creates a passivation layer on the steel. The passivation layer prot......

X1CrNiMoN25-22-2 application
1. Introduction
UNS S31254 (1.4547) or ASTM A182 F44, also known as Alloy 254 SMO, is a high-end stainless steel and one of the most common super austenitic grades. It increases the corrosion resistance of stainless steel by making it airtight and adding molybdenum and nitrogen. This combination ......
French standard steel number representation method
France uses several steel numbering systems, including the French Standard or AFNOR, the France-based UIC Standard, and the France-based EN Standard.
AFNOR steel grades are commonly designated using the following format:
XCXX–XX–XX, where:
• XC represents the steel category, e.g. XC18 = gener......
