17 4 Stainless Steel Vs 304

Precipitation hardening grade is a combination of two stainless steel structures i e.

17 4 stainless steel vs 304.

What is type 304 stainless steel and what s it used for. Most of the parts of that ship that you went on that annual cruise are made from type 17 4 ph stainless steel. It is also known as 630 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.

Type 304 with its chromium nickel content and low carbon is the most versatile and widely used of the austenitic stainless steels. The numbers 17 4 refer to its composition. Type 304 proves to be resistant to oxidation corrosion and durability. And precipitation hardened stainless steels like grades 17 4 ph and 15 5 ph.

Both steels are durable and provide excellent resistance to corrosion and rust. Very high strengths can be achieved with martensitic stainless steels like grade 440c. 17 chromium and 4 nickel. Ss316 and 17 4 ph are one of the most important stainless steel grades.

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

There are several factors that come into play when choosing the type of stainless steel to use. Its alloys are all modifications of the 18 chromium 8 nickel austenitic alloy. Mechanical properties such as strength and ductility can be optimized with heat treatment. Examples of these are grade 440c and 17 4 ph respectively.

Type 17 4 ph stainless steel contains between 15 17 5 of chromium in its composition. 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. In this regard a seagoing vessel s pump and valve parts are made of type 17 4 ph stainless steel.

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. 304 stainless steel is the most versatile and widely used austenitic stainless steel in the world due to its corrosion resistance.
