17 4 Stainless Steel Vs 304

17 chromium and 4 nickel.

17 4 stainless steel vs 304.

Ss316 and 17 4 ph are one of the most important stainless steel grades. The numbers 17 4 refer to its composition. 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.

304 stainless is also cheaper in cost compared to 316 another reason for its popularity and widespread use. When you compare stainless steel 17 4 ph vs 316 it is obvious that 17 4 ph has higher hardening content. Both steels are durable and provide excellent resistance to corrosion and rust. It is also known as 630 stainless steel.

Its alloys are all modifications of the 18 chromium 8 nickel austenitic alloy. Very high strengths can be achieved with martensitic stainless steels like grade 440c. Austenitic stainless steels such as grade 316 can provide. 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. Deciding whether to use grade 303 vs 304 stainless steel often comes down to determining what the application will be. Type 17 4 ph stainless steel contains between 15 17 5 of chromium in its composition. Mechanical properties such as strength and ductility can be optimized with heat treatment.

Type 304 with its chromium nickel content and low carbon is the most versatile and widely used of the austenitic stainless steels. What are the strength requirements of the stainless steel. 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. 316 and 17 4ph are austenite and precipitation hardening material grades respectively which are defined in american standards.

Type 304 proves to be resistant to oxidation corrosion and durability. Most of the parts of that ship that you went on that annual cruise are made from type 17 4 ph stainless steel. 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. 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.

Precipitation hardening grade is a combination of two stainless steel structures i e. 304 stainless steel is the most versatile and widely used austenitic stainless steel in the world due to its corrosion resistance.
