17 4 Ph Stainless Steel Vs 316

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

17 4 ph stainless steel vs 316.

Known for its corrosion resistance characteristics stainless steel is a widely used alloy comprised of a minimum of 10 5 chromium by mass. The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel. 17 4 ph vs 316 offer high corrosion resistance. Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4.

This article will focus on two types in particular. 17 4 and 316l 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. Farmers copper is an industry leading stainless steel supplier.

It contains approximately 15 17 5 chromium and 3 5 nickel as well as 3 5 copper. Various ph levels can cause 17 4 ph material to generate mineral deposits and clog process connections. Well 17 4 ph is a martensitic precipitation hardened steel that combines high strength and hardness with excellent corrosion resistance. Both the grades i e.

316l is a great general purpose steel. Also known as uns 17400 is a grade of martensitic precipitation hardened stainless steel. We maintain a large inventory of various stainless steel grades including 218 303 304 316 17 4 ph and more. Gases such as hydrogen require 316l material.

The numbers 17 4 refer to its composition. 316l also offers excellent corrosion resistance and low levels of carbon which make it great for welding. Hydrogen ions are small enough to penetrate the grain structure of 17 4 ph stainless steel thus breaking down the diaphragm over time as a result of embrittlement.
