316L(Cr-Ni-Mo)

1. Introduce

– 316L stainless steel is engineered to have improved corrosion resistance over 300 series and lower stainless steels

– Corrosion resistance and high temperature strength are improved over grade 304 by the addition of approximately 2-3% Mo

– Low carbon version of 316
→ Alloy designed to minimize carbide precipitation and improve weldability

– UNS S31603

* 316 Stainless steel type : Related to carbon content

: 316 series is a material with improved resistance to acid and localized corrosion from chloride environment by adding about 2-3% Mo

: Carbon content: Higher carbon content improves thermal stability and creep strength, lower carbon content improves weldability

– 316L : Carbon content 0.030% Maximum

– 316 : Carbon content 0.08% Maximum

– 316H : Carbon content 0.04~0.10% Maximum

* UNS

1. Abbreviation for the Unified Numbering System for Metals and Alloys
2. Unified unique numbering system for metals and alloys
3. A representative number compatible with metals and alloys defined in several material-related codes, including ASTM, AISI, ASME, AWS, etc.

* S : Heat and corrosion resistant (stainless) steel

2. Property

– High temperature strength, strength, corrosion resistance, abrasion resistance, weldability, good machinability
