Ferritic stainless steel

Grade 405 - due to its weaker corrosion resistance, grade 405 stainless steel is appropriate for mild corrosive applications. Grade 405 SS does not harden when the material is cooled after welding procedures because of the additional aluminium it contains. It is used for applications like steam nozzles and quenching racks.

Grade 408 - although this type of stainless steel has weak corrosion resistance, it has good heat resistance. It is made from a combination of 8% nickel and 11% chromium.

Grade 409 - both high-temperature tolerance and corrosion resistance characteristics are present in grade 409. It is particularly resistant to exhaust gas and atmospheric corrosion and is consequently used in automobile applications, including exhaust systems.

Grade 420 - With 12% chromium and a 50HRC hardness, this grade of stainless steel is the hardest of all the grades. It also has good ductility and corrosion resistance, particularly against alkalis, fresh water, foods, and mild acids. Grade 420 stainless steel is often used to make cutlery, though prolonged exposure to certain food substances can cause pitting.

Duplex stainless steel

Grade 2205 - with the addition of nitrogen, grade 2205 stainless steel is intended to withstand stress corrosion cracking, pitting, and crevice corrosion. As a result, grade 2205 has corrosion resistance that is over two times greater than that of other austenitic steels. Applications needing high strength and great corrosion resistance are used grade 2205 in the oil and gas, petrochemical, maritime, and pulp and paper sectors.

Grade 2304 - grade 2304 has over twice the yield strength of grade 316 and comparable austenitic steels yet has the same level of corrosion resistance. It can also function well in cooler climates, with few exceptions. Most uses for this material fall between -58°F and 572°F.

Grade 2507 - this duplex stainless steel has a low coefficient of thermal expansion, strong chloride stress corrosion resistance, and high thermal conductivity. Applications requiring exceptional corrosion resistance and high tensile strength are best served by grade 2507. Applications for grade 2507 stainless steel include offshore oil platforms, marine and petrochemical equipment, and various mechanical and structural parts.

Martensitic stainless steel

Grade 410: grade 410 is a general-purpose martensitic stainless steel that offers corrosion resistance properties that can be enhanced through hardening, polishing, and tempering. Even though martensitic stainless steel alloys like grade 410 perform well in mild corrosive settings, they are not as corrosion-resistant as austenitic steels.

Grade 414: grade 410 stainless steel is essentially grade 410 with nickel added. Nickel addition also makes it more robust than grade 410. This steel is frequently used to create valve seats, beater bars, forged shafts and spindles, fasteners, and mining equipment.

Grade 416: grade 416 stainless steel boasts the highest machinability of any stainless steel with a rating of 85%. Considering this property and its affordability, grade 416 stainless steel is available in a range of finishes, including severely tempered, hardened, and unhardened. Although grade 416 is extremely resistant to fresh water, acids, and alkalis, it has less corrosion resistance than austenitic steels. Automatic screw-machined parts, gears, bolts, and washing machine parts are common uses.
