Stainless steel 317LN is a nitrogen alloyed austenitic stainless steel having high nitrogen content than other austenitic stainless steels. It has higher yield and tensile strength than 317L.
Stainless steel grade 439 is capable of being made into complex shapes such as tubular manifolds and exhaust system components, where temperatures tend to go beyond the oxidation limit of grade 409 steel.
Stainless steel grade 440A is a high carbon martensitic stainless steel that possesses good strength, moderate corrosion resistance, and excellent hardness and wear resistance.
The Academy of Motion Picture Arts and Sciences honors achievement in film and filmmaking through nine annual awards, with the Academy Award of Merit or the Oscar being the most popular and coveted trophy.

Stainless steel 15-7 Mo is a semi-austenitic and precipitation hardening stainless steel that provides good corrosion resistance, high hardness and strength and minimum distortion on heat treatment.
The 200 series stainless steels posses a lesser content of nickel than the 300 series austentic stainless steels. Grade 201 is a cheaper alternative to traditional Cr-Ni austenitic stainless steels such as grade 304.
Grade 201 is a cheaper alternative to the traditional Cr-Ni austenitic stainless steels such as grade 304. Grade 201LN stainless steel has good resistance to oxidation, easy fabrication, and excellent toughness even in low temperatures.
Grade 202 stainless steel is a type of Cr-Ni-Mn stainless with similar properties to A240/SUS 302 stainless steel. The toughness of grade 202 at low temperatures is excellent.
Grade 205 stainless steel is an austenitic standard grade. It is also referred to as AISI Type 205 Chromium-Manganese-Nickel steel. Grades such as the 205-series provide approximately 30% higher mechanical properties such as yield strength than the traditional 304-series.
Grade 301 is a cheaper alternative to the traditional high-nickel austenitic stainless steels such as grade 304. Grade 301L stainless steel is a low carbon steel which is ideal for improved ductility and when heavy sections are to be welded.
