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 proves to be resistant to oxidation corrosion and durability. Type 304 stainless is austenitic and non magnetic meaning it also provides low thermal and electrical conductivity. 304 stainless is also cheaper in cost compared to 316 another reason for its popularity and widespread use. Examples of these are grade 440c and 17 4 ph respectively.

It is also known as 630 stainless steel. Very high strengths can be achieved with martensitic stainless steels like grade 440c. Its alloys are all modifications of the 18 chromium 8 nickel austenitic alloy. Ss316 and 17 4 ph are one of the most important stainless steel grades.

Deciding whether to use grade 303 vs 304 stainless steel often comes down to determining what the application will be. 304 stainless steel is the most versatile and widely used austenitic stainless steel in the world due to its corrosion resistance. Both steels are durable and provide excellent resistance to corrosion and rust. 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.

When you compare stainless steel 17 4 ph vs 316 it is obvious that 17 4 ph has higher hardening content. What are the strength requirements of the stainless steel. The numbers 17 4 refer to its composition. And precipitation hardened stainless steels like grades 17 4 ph and 15 5 ph.

There are several factors that come into play when choosing the type of stainless steel to use. 316 and 17 4ph are austenite and precipitation hardening material grades respectively which are defined in american standards. Austenitic stainless steels such as grade 316 can provide. 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.

Mechanical properties such as strength and ductility can be optimized with heat treatment. 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. Precipitation hardening grade is a combination of two stainless steel structures i e. Most of the parts of that ship that you went on that annual cruise are made from type 17 4 ph stainless steel.

In this regard a seagoing vessel s pump and valve parts are made of type 17 4 ph stainless steel. 17 chromium and 4 nickel.
