17 4 Stainless Steel Vs 316

17 chromium and 4 nickel.

17 4 stainless steel vs 316.

Ss316 and 17 4 ph are common used two types of stainless steel grades for investment casting. This article will focus on two types in particular. Standard 316l is slightly magnetic but non magnetic versions are available. 17 4 and 316l stainless steel.

The 17 4 ph stainless steel is magnetic and less corrosion resistant than 316l stainless steel. Both the grades i e. 316 is typical austenite stainless steel casting grade while 17 4 ph stainless steel is precipitation hardening material grade which are all defined in american standards. 17 4 ph vs 316 offer high corrosion resistance.

Precipitation hardening grade is a combination of two stainless steel structures i e. 17 4 ph steel has been chosen by waukesha and copied by others because of the extended service it offers under extreme conditions. Almost at any condition the corrosion resistance for 316 is better than 17 4. The numbers 17 4 refer to its composition.

17 4 comparable to 302 304 is desgined mainly for high strength with some corrosion resist tbuelna aerospace 2 dec 14 23 12 more details about the application where these parts were used over the 3 year period would be helpful especially some photographs. But it isn t 316 and you re not quite sure why that matters but you have a piece of paper in front of you that says it does so go on and elaborate.
