17 4 Stainless Steel Vs 316

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.

17 4 stainless steel vs 316.

One distinguishing factor are the 17 4 ph shafts. 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 17 4 ph stainless steel is magnetic and less corrosion resistant than 316l stainless steel.

Both the grades i e. Standard 316l is slightly magnetic but non magnetic versions are available. 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. 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.

Precipitation hardening grade is a combination of two stainless steel structures i e. 17 4 and 316l stainless steel. This article will focus on two types in particular. 17 chromium and 4 nickel.

The numbers 17 4 refer to its composition. When you compare stainless steel 17 4 ph vs 316 it is obvious that 17 4 ph has higher hardening content.
