With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Stainless steels are used at temperatures up to 1700 F for 304 and 316 and up to 2000 F for the high temperature stainless grade 309(S) and up to 2100 F for 310(S). Stainless steel is used extensively in heat exchangers, super-heaters, boilers, feed water heaters, valves and main steam lines as well as aircraft and aerospace applications.
Type 201 stainless cannot be hardened by heat treatment, but can by cold working. Type 201 can be annealed at temperatures between 1010 and 1093C (1850 and 2000F). In order to keep carbides in solution and avoid sensitization, rapid cooling through the carbide precipitation range 815 and 426C (1500 and 800F) is required.
temperature or at intermittently high temperature. For a prolonged service life, such as 20 years, plain carbon steels are usually limited to a maximum operating temperature of 750F (399C); the % molybdenum alloy steels to approximately 850F (454C); and the stainless steels to considerably higher temperatures depending upon the type used.

Stainless Steel Datasheets Revised November 2011 Page 1 of 1 www.atlassteels.com.au Austenitic Stainless Steels 301, 301L, 301LN High strength for roll formed structural components 302HQ Low work hardening rate grade for cold heading fasteners 303, 303Se Free-machining bar grades 304, 304L, 304H Standard 18/8 grades
Austenitic stainless steels are extensively used for service down to as low as liquid helium temperature (-269 deg C). This is largely due to the lack of a clearly defined transition from ductile to brittle fracture in impact toughness testing. Toughness is measured by impacting a small sample with a swinging hammer.
Type 410 is hardenable, straight-chromium stainless steels which combine superior wear resistance of high carbon alloys with the excellent corrosion resistance of chromium stainless steels. Oil quenching these alloys from temperatures between 1800F to 1950F (982-1066C) produces the highest strength and/or wear
The 200 series grades perform at a similar level to grades 304 and 301 in low corrosion, mainly indoor applcations at room temperature. Not recommended for use in Chloride environments.
The annealing temperature for Type 201 is between 1850-2000F. Rapid cooling through the carbide precipitation range (1500 800 o F) is necessary to keep the carbides in solution and prevent sensitization. Type 201 is not hardenable by thermal treatment; it is only hardenable by cold working. Forming:
range of 1150C to 1250C is required. The finishing temperature should not be below 900C. Upsetting operations and forgings require a finishing temperature between 930C and 980C. Forgings should be air cooled. All hot-working operations should be followed

Types 316 and 316L are molybdenum-bearing austenitic stainless steel which are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium nickel austenitic stainless steel such as Type 304. These alloys also offer higher creep, stress-to-rupture and tensile strength at elevated temperature.
Stainless Steel - Grade 304 CS 304 / 304L Technical Data. Grade 304 stainless steel is the most versatile and the most widely used of all stainless steels. Its chemical composition, mechanical properties, weldability and ncorrosion/oxidation resistance provide the best all-round performance stainless steel at relatively low cost.
temperatures above about 500C and up to about 800C. 304H will become sensitised in the temperature range of 425860C; this is - not a problem for high temperature applications, but will result in reduced aqueous corrosion resistance.

Stainless steel grade 430 is capable of resisting oxidation up to 870C (1598F) in intermittent usage, and up to 815C (1499F) in continuous usage. At room temperature, it has the tendency to become brittle, especially when it has been heated for a long time in the 400-600C (752-1112F) range.
Stainless steel is used for buildings for both practical and aesthetic reasons. Stainless steel was in vogue during the art deco period. The most famous example of this is the upper portion of the Chrysler Building (pictured). Some diners and fast-food restaurants use large ornamental panels and stainless fixtures and furniture.
USS Triton (SS-201), a Tambor-class submarine, was the first submarine and third ship of the United States Navy to be named for Triton, a mythological Greek god, the messenger of the sea. Her keel was down on 5 July 1939 by the Portsmouth Navy Yard.

Melting temperature ranges for stainless steels Introduction. Stainless steels are alloys and therefore do not melt and freeze at a fixed temperature, as do metallic elements, but over a temperature range, depending on the chemical composition of the steel. Alloy additions also suppress (lower) the melting range.
//// Alloy 200 (UNS designation N02200) and Alloy 201 (UNS designation N02201) are wrought commercially pure nickel. The alloys differ only in the maximum carbon level allowed by specification, 0.15 % maximum for Alloy 200 and 0.02 % maximum for Alloy 201. Both alloys provide highly ductile mechanical properties over a wide temperature range.
Stainless steel alloys tend to possess a strong, but thin, layer of oxide that prevents rusting, hence the name stainless steel. In mildly corrosive environments at normal ambient temperatures, the corrosion resistance of grade 301 and grade 304 stainless isnt very different.
The table below shows mechanical properties of stainless steels at low temperatures. Elongation is an indication of their good ductility. There is an increase in tensile and yield strengths as the temperature decreases as well. Mechanical Properties of 304, 321 and 316 Stainless Steels at Cryogenic Temperatures.
Type 301 (UNS Designation S30100) GENERAL PROPERTIES Type 301 (S30100) is an austenitic stainless steel with a nominal composition of 17 percent chromium and 7 percent nickel. The high strengths of this grade of steel in the six available conditions or tempers, its resistance to atmosphere corrosion and its bright, attractive surface make it an
It was developed for use in the chromium carbide precipitation range of 800 1500F (427 816C) where un-stabilized alloys such as 304 are subject to intergranular attack. In this temperature range, the overall corrosion resistance of Alloy 347 stainless steel plate is superior to Alloy 321 stainless steel plate.
303 is a free machining chromium-nickel austenitic stainless steel with good strength and good corrosion resistance, as supplied in the annealed condition with a typical brinell hardness of 190. Characterised by excellent machinablity and non galling properties due to its higher sulphur content, which has the effect of lowering slightly its ss sus 201 temperature range

Grade 304 is a standard "18/8" stainless. It is the most versatile and most widely used stainless steel available, even though a wide range of alternatives are available; and has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing.
Stainless Steel - Grade 316 Grade 316 / 316L Technical Data Summary. Grade 316 is an improved version of CS 304, with the addition of molybdenum and a slightly higher nickel content.
