17 4 Stainless Steel Vs 304

Mechanical properties such as strength and ductility can be optimized with heat treatment.

17 4 stainless steel vs 304.

Both steels are durable and provide excellent resistance to corrosion and rust. Most of the parts of that ship that you went on that annual cruise are made from type 17 4 ph stainless steel. Type 304 stainless is austenitic and non magnetic meaning it also provides low thermal and electrical conductivity. When you compare stainless steel 17 4 ph vs 316 it is obvious that 17 4 ph has higher hardening content.

Type 304 with its chromium nickel content and low carbon is the most versatile and widely used of the austenitic stainless steels. It is also known as 630 stainless steel. Examples of these are grade 440c and 17 4 ph respectively. 304 stainless is also cheaper in cost compared to 316 another reason for its popularity and widespread use.

Type 17 4 ph stainless steel contains between 15 17 5 of chromium in its composition. Type 304 proves to be resistant to oxidation corrosion and durability. Its alloys are all modifications of the 18 chromium 8 nickel austenitic alloy. What is type 304 stainless steel and what s it used for.

And precipitation hardened stainless steels like grades 17 4 ph and 15 5 ph. 17 4 stainless steel also known as sae type 630 is a common and exceptionally durable type of steel used in a diverse variety of industries and applications. Austenitic stainless steels such as grade 316 can provide. Very high strengths can be achieved with martensitic stainless steels like grade 440c.

High strength 17 4 ph stainless steel with a higher chromium content than 15 5 ph stainless steel this high strength 17 4 ph offers better corrosion resistance. The numbers 17 4 refer to its composition. In this regard a seagoing vessel s pump and valve parts are made of type 17 4 ph stainless steel. Precipitation hardening grade is a combination of two stainless steel structures i e.

316 and 17 4ph are austenite and precipitation hardening material grades respectively which are defined in american standards. Deciding whether to use grade 303 vs 304 stainless steel often comes down to determining what the application will be. 17 chromium and 4 nickel. There are several factors that come into play when choosing the type of stainless steel to use.

It also can include between 3 and 5 copper. What are the strength requirements of the stainless steel.
