SAE 316L grade stainless steel, sometimes referred to as A4 stainless steel or marine grade stainless steel, is the second most common austenitic stainless steel after 304/A2 stainless steel. Its primary alloying constituents after iron , are chromium (between 16–18%), nickel (10–12%) and molybdenum (2–3%), up to 2% manganese , [ 1 ] with ...
Applications for superaustenitic stainless steel alloy AL-6XN include chemical processing, oil and gas, medical – sterilization and power generation [3] with specific applications identified in desalination, water piping systems. transformer cases in marine environments, food processing equipment, FGD scrubbers, reverse osmosis, and heat exchangers.
Type 308—used as the filler metal when welding 304. Type 309—better temperature resistance than 304, also sometimes used as filler metal when welding dissimilar steels, along with inconel. Type 310 310S— is a highly alloyed austenitic stainless steel used for high temperature application. The high chromium and nickel content give the ...

Alloy 20 (Carpenter 20) is an austenitic stainless steel possessing excellent resistance to hot sulfuric acid and many other aggressive environments which would readily attack type 316 stainless. This alloy exhibits superior resistance to stress-corrosion cracking in boiling 20–40% sulfuric acid.
The AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification. For steel construction (civil engineering structures) AWS D1.1 is a widely used standard.
SAE 316 stainless steel is a molybdenum-alloyed steel and the second most common austenitic stainless steel (after grade 304). It is the preferred steel for use in marine environments because of its greater resistance to pitting corrosion than most other grades of steel without molybdenum. [ 1 ]
SAE 316 and SAE 316L stainless steel, also referred to as marine grade stainless, is a chromium, nickel, molybdenum alloy of steel that exhibits relatively good strength and corrosion resistance. 316L is the low carbon version of 316 stainless steel. [2] 316L in particular is biocompatible when produced to ASTM F138 / F139. [3]
