Stainless Precision Ground Steel Bar

There is no denying that stainless steel has given the world a lot of applications ranging from construction to healthcare to transportation. Everyone is thankful that stainless steel improvements were made when it was initially invented. Before you get your hands on stainless steel round bar supplier, let's get to know more about it below.

Stainless Steel History

Let’s have a trip down to memory lane with stainless steel, unlike iron, which has been in use for over 1,000 years. It was always the steel that everyone got used to using. Meanwhile, stainless steel is a relatively new material, which is why there is an increase in sellers, and you need to pick out the best stainless steel round bar supplier.

It was around 100 years ago the first stainless steel was created. It was a big deal when Harry Brearley created the first real stainless steel in 1913. This metal was found to be resistant to both corrosion and rust when he added chromium to iron at a concentration of 12.8%.

1919, a patent application for marensitic stainless steel, a predecessor to today’s 410 stainless steel, was filed in the United States. In 1929, William J. Kroll discovered the process of precipitation-hardening stainless steel, which he named after his father. Then, the first duplex stainless steel was created in Sweden in 1930, and it is still in use today.

Stainless Steel Grades

Stainless steels come in various types, each with its own advantages and disadvantages. It is classified into five categories. However, only three types are typically used in multiple applications. Check them out below to know which precision ground steel bar is the best for you.

Austenitic Stainless Steels

Austenitic stainless primary crystalline structure is austenite. It prevents heat treatment hardening and renders steels non-magnetic. It has two subgroups: the 300 series, which are austenitic due to the nickel content, and the 200 series are austenitic due to the manganese and nitrogen content.

Ferritic Stainless Steel

Ferritic steel is a high chromium stainless steel alloy that differs from other stainless steel alloys in two key ways: chemical composition and molecular grain structure. It is a non-hardenable straight chromium alloy with a chromium content of 10.5-30% and carbon content of less than.20%. 409, 430, 439, 442, and 446 Stainless are common ferritic stainless grades.

Martensitic stainless steel

In terms of structural similarities, martensitic stainless steels are identical to ferritic stainless steels. While ferritic stainless steel has a carbon content below 0.10 percent, martensitic stainless steel has a carbon content of about 1%. The most popular grades are 410, 420, and 440A Stainless steel.

Duplex and precipitation hardened are the two other categories of Stainless steel. These are precision ground steel bar choices that you get. Due to the duplex’s metallurgical structure, it includes about equal amounts of austenite and ferrite. They are stronger and more resistant to corrosion than ordinary austenitic stainless steels like Type 304 or 316.

Meanwhile, Precipitation hardened grades use temperature-dependent changes in solid solubility to form tiny particles of an impurity phase that obstruct dislocation movement. Because dislocations often carry plasticity, they serve to harden the material. It is known to cause high-temperature yield strength anomalies.
