These bars are supplied in a variety of lengths starting from 1 to 16 metres. We can make these bars in bespoke sizes to meet the needs of clients. When stainless steel 420 is annealed and stiffened, it achieves superior mechanical qualities. Dental and medical equipment, pipelines, valves and nozzles, industrial equipment, and other industries can all benefit from our 420 stainless steel bars. 420 SS is often used with high strength, light corrosion, and heat resistance. Based on the quality standards, we only provide 420 stainless steel forging comparable.

These bars are also utilised in kitchenware and cooking utensils, water and steam cooling fins, fasteners, and valves parts, as well as aeronautical, military, petroleum, and biomedical sectors. Our goods are subjected to several testing to assure the highest quality. Mechanical tests such as tensile of area, hardness test, spectro analysis, flatness testing, macro and micro testing, and intergranular corrosion or IGC testing are some of these tests.

What is Stainless Steel 420 Black Bar?

SS 420 Black Bar is a general purpose medium carbon straight chromium high hardenability martensitic stainless steel with good strength and fairly good corrosion resistance. It is generally supplied hardened and tempered either in the tensile range 700 – 850 Mpa (condition R) Brinell range 201 – 255, or in the tensile range 770 – 930 Mpa (condition S)Brinell range 223 – 277 or in the annealed condition with a maximum Brinell hardness of 241.Characterised by good corrosive resistance in mild atmospheric, domestic and industrial environments. It is resistant to ammonia, blood, carbonic acid, crude oil, detergent solutions, dilute nitric acid, fresh water, food acids, many petroleum products, steam and vinegar etc.
