What is the use of stainless steel bar?
You will find stainless steel bars used in almost every industry, but some common applications by shape include:
Stainless steel flat bars
- Brackets/braces on fixtures
- Ornamental work
Stainless steel hexagon bars
- Construction application
- These bars typically run through a screw machine to produce parts
Stainless steel round bars
- Machined parts for many industries
- Automotive components
- Sprinkler heads
What are the types of stainless steel bars?
17-4/Type 630 combines high strength and hardness with corrosion resistance. Simple low-temperature heat treatment at 900/11508F eliminates scaling and can prevent excessive warpage.
17-4 Doubled Aged H1150 is annealed and then double-age hardened to procedure #1 in NACE MR 01-75. This grade is commonly used in pressure control applications for the energy market.
303 Stainless Steel Bar is a free-machining variation of T302/304 and is corrosion-resistant to atmospheric exposures, sterilizing solutions, most organic and many inorganic chemicals, most dyes, nitric acids, and foods.
304 Stainless Steel Bar is a heat-resistant grade offering good corrosion resistance to many chemical corrodents, as well as industrial atmospheres. This grade exhibits good formability and can be readily welded by all common methods. An extra low carbon variation, called 304L, avoids harmful carbide precipitation due to welding. This variation offers the same corrosion resistance as 304, but with slightly lower mechanical properties.
316 Stainless Steel Bar is a commonly used grade of stainless steel bar, featuring higher resistance to corrosion and pitting than 304 and offers higher strength at elevated temperatures. An extra low carbon variation (316L) helps avoid carbide precipitation due to welding.
410 Stainless Steel Bar is a heat-treatable grade of stainless steel bar that is ideally suited for use in environments where corrosion is not severe, including air, freshwater and with some chemicals and food acids. A quenched and double tempered variation is used for parts in hydrogen sulfide service.
416 Stainless Steel Bar is a ”free-machining variation” of 410 that features useful corrosion resistance to natural food acids, basic salts, water, and most atmospheres.
