17 4 Stainless Steel Vs 304

What is type 304 stainless steel and what s it used for.

17 4 stainless steel vs 304. Type 304 stainless is austenitic and non magnetic meaning it also provides low thermal and electrical conductivity. Austenitic stainless steels such as grade 316 can provide. Both steels are durable and provide excellent resistance to corrosion and rust. 17 4 ph stainless steel uns s17400 is a precipitation hardenable martensitic stainless steel that delivers an excellent combination of oxidation and corrosion resistance and is comparable to 304 in most conditions or environments.

When you compare stainless steel 17 4 ph vs 316 it is obvious that 17 4 ph has higher hardening content. Examples of these are grade 440c and 17 4 ph respectively. Most of the parts of that ship that you went on that annual cruise are made from type 17 4 ph stainless steel. 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. The numbers 17 4 refer to its composition. Mechanical properties such as strength and ductility can be optimized with heat treatment. And precipitation hardened stainless steels like grades 17 4 ph and 15 5 ph.

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. What are the strength requirements of the stainless steel. Type 304 proves to be resistant to oxidation corrosion and durability. 17 chromium and 4 nickel.

Precipitation hardening grade is a combination of two stainless steel structures i e. It also can include between 3 and 5 copper. In this regard a seagoing vessel s pump and valve parts are made of type 17 4 ph stainless steel. Very high strengths can be achieved with martensitic stainless steels like grade 440c.

There are several factors that come into play when choosing the type of stainless steel to use. Type 304 with its chromium nickel content and low carbon is the most versatile and widely used of the austenitic stainless steels. Ss316 and 17 4 ph are one of the most important stainless steel grades. 316 and 17 4ph are austenite and precipitation hardening material grades respectively which are defined in american standards.

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. Deciding whether to use grade 303 vs 304 stainless steel often comes down to determining what the application will be.
