What guns are made from stainless steel?
Stainless Steels Stainless-steel barrels have become a popular choice for competition rifles, varmint rifles, all-weather rifles, combat handguns and marine shotguns. An especially popular stainless steel alloy used by many barrel makers is called 416R.
Why are guns not made of stainless steel?
Developed before World War I, stainless steel used in firearms isn’t really stainless. It is very rust-resistant, however — not because there is so much chromium but because the chromium on the surface reacts to air to form a passive layer of chromium oxide, which seals the iron from oxidation.
When did stainless steel become common?
In 1924, Hatfield patented the 18-8 stainless steel, 18% chromium and 8% nickel. This austentic stainless would soon rise to become the most popular and widely used type of stainless steel.
How did Harry Brearley discover stainless steel?
So we come now to Harry Brearley. In 1912, in Sheffield, while seeking a corrosion-resistant alloy for gun barrels during his work at the Brown-Firth research laboratory, Brearley discovered a martensitic stainless steel alloy. The discovery was mentioned in a January 1915 newspaper article in The New York Times.
Is a stainless barrel more accurate?
Over 90% of high-grade match barrels are made from Stainless Steel. Stainless is easier to machine because it is slightly softer. That said, chrome-moly barrels can be just as accurate, when made correctly, and there is evidence a chrome-moly barrel will hold its accuracy longer than a stainless barrel.
How old was Harry Brearley when he invented stainless steel?
Harry was born into a poor family. His father was a steel worker at Thomas Firth & Sons. He started working at the age of twelve and a couple of years later was working Firth’s as a bottle washer in the chemical laboratory. He studied metallurgy and learnt very quickly….

Stainless steel/Inventors
Harry Brearley invented the first true stainless steel in 1913. He added 12.8% chromium to iron, and produced a metal that he found was resistant to both corrosion and rust. Brearley discovered this metal while looking for a solution to the problem of erosion in the gun barrels of the British army.
How is the invention of stainless steel related to firearms?
Fittingly, the invention of stainless steel was actually related to firearms. Harry Brearley, an English chemist was working in Sheffield, England for Brown Firth research labs in 1912, trying to find a new steel that could resist erosion caused by high temperatures of gun barrels.
What kind of steel is used in firearms?
Like chrome-moly steels, there are also different grades of stainless steels and only some grades are used in the manufacture of firearms. For instance, SAE grades 410 and 416 are used for firearms barrels. They are both steel alloys with high chromium content (11.5 – 13.5% for 410 stainless steel and 12-14% for 416 stainless steel).
What was the first type of stainless steel?
In 1924, Hatfield patented the 18-8 stainless steel, 18% chromium and 8% nickel. This austentic stainless would soon rise to become the most popular and widely used type of stainless steel.
When was the first stainless steel revolver made?
Until, all of a sudden, in 1965, S&W introduced the Model 60 revolver, a stainless-steel version of the company’s popular .38-caliber Chief ’s Special. Other firearms manufacturers took notice, and began to think seriously about stainless steel as a material for guns.
