Stainless steel alloys are iron based alloys, with the secondary material being chromium (typically 4% – 30% of the total of the alloy). These alloys are also typically comprised of carbon, aluminum, titanium, copper, nickel, and other elements.
Stainless steel is widely used across many sectors, and it is expected that the demand for stainless steel will continue to grow. In 2019 alone, the global production of stainless steel exceeded 52 million tons. It’s no wonder why stainless steel is so sought after. These alloy forgings are made to be incredible strong and resilient, and are highly resistant to various corrosive elements, especially heat. When forged properly, stainless steel forged parts are made to have incredible strength and are resistant to many forms of decay, like rust.
Weldaloy Specialty Forgings produces open die forged parts and seamless rolled rings in a variety of materials, including stainless steel. Our team of engineers, metallurgists, and quality personnel ensure that our parts meet quality standards, and the needs of our customers.
Certain grades of stainless steel are used for kitchen appliances. This accounts for the use of most of the stainless steel being manufactured today. However, there are industrial grade stainless steel alloys that are used in many different applications. Industries that regularly use stainless steel alloys include:
Certain stainless-steel alloys are generally considered easily forgeable and can be made into a variety of part shapes. Commonly forged stainless-steel parts include:
There are over 200 different grades of stainless steel alloys. These alloys are placed into five distinct categories – austenitic, martensitic, ferritic, duplex, and precipitation hardening. These categories represent the crystalline structure of the stainless steel alloys. All the categories of stainless steel alloys are manufactured to have incredible strength and resistance to corrosion.
Austenitic – Austenitic steel alloys is the largest categories of stainless steel. Roughly two-thirds of all stainless steel production are austenitic alloys. The name comes from it also having the highest impact strength out of all stainless steel grades. Austenitic alloys consist of 200 and 300 series alloys.
Martensitic – Martensitic grades of stainless steel alloys are highly resistant to pitting corrosion and are very strong. Martensitic alloys are also known for being formable and weldable. Martensitic alloys are used for various tools (cutlery, dental instruments, scissors, screwdrivers, stable guns, pliers and industrial blades), and cookware.
Ferritic – Ferritic grades of stainless steel alloys are high in chromium and low in carbon. They are magnetic steel alloys that have good ductility, and high resistance to corrosion and stress corrosion cracks. This grade is fairly strong and tough, with a good fatigue life. Ferritic alloys are used for applications that requiring thinner materials and lighter weight. Ferritic Stainless Steel alloys are 400 series steel alloys.
Duplex – Duplex stainless steel as a unique microstructure, in that it consists of both austenitic and ferrite characteristics (roughly 50% of each). Used mostly in the oil and gas industry, duplex stainless steel contains more nitrogen then other grades of steel. As a result, duplex alloys are more weldable grades of steel, while maintaining toughness at room temperature, and have incredible strength and resistant to corrosion and stress corrosion cracks.
Precipitation Hardening – Precipitation hardening stainless steel alloys are different from other steel alloys as they contain small additions of copper, aluminum, phosphorus, or titanium. After a part of a precipitation hardening steel alloy is made, it typically is given an age-hardening treatment in which these elements precipitate as hard intermetallic compounds that significantly increase hardness and strength.
