What is UNS S30403?
ASTM A182 UNS S30403 is a forging material specification for S30403 grade stainless steel and is used for manufacturing bare forgings or forged and machined products for applications involving high temperature service.
What is the difference between 316L and 304L stainless steel?
Type 316L is resistant to sulfuric acid only when it is at low concentration, whereas type 304L is resistant to sulfuric acid even when it is in high concentration. Grade 304L stainless steel has greater capability than grade 316L to break down and absorb energy without disintegrating.
Is 304 better than 304L?
Type 304 and 304L have very similar chemical and mechanical properties. The only difference between them is the carbon content; the 304 stainless steel has a maximum range of carbon of 0.08% whereas the 304L has a maximum range of 0.03%. As a result, it significantly reduces corrosion resistance of steel in this zone.
Is 316 stainless machinable?
Grade 316 steel has a machinability rating of 60, while 316B has a machinability rating of 50. Grade 304 and 304L have the same machinability rating of 70 by American Iron and Steel Institute or AISI standards. For comparison, alloy 303 is the most easily machined stainless steel.

What is 304L steel made of?
Alloy 304/304L (UNS S30400/ S30403) is the most widely utilized “18-8” chromium-nickel austenitic stainless steel. It is an economical and versatile corrosion resistant alloy suitable for a wide range of general purpose applications. It is common practice for 304L to be dual certified as 304 and 304L.
What is the US Code for 304 stainless steel?
Specification Sheet: Alloy 304/304L (UNS S30400, S30403) W. Nr. 1.4301, 1.4307 Most Widely Used Austenitic Stainless Steel, a Versatile Corrosion Resistant Alloy for General Purpose Applications
What is the corrosion resistance of 304L?
Alloy 304/304L has good resistance to atmospheric corrosion, foods and beverages and to many organic and inorganic chemicals in moderately oxidizing to moderately reducing environments. The high chromium content of the alloy provides resistance to oxidizing solutions such as nitric acid up to 55% weight and up to 176°F (80°C).
