With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
The temperature tolerance of grade 316 stainless steel is close to that of grade 304, being just a little bit lower. As stated in an AK Steel data sheet for grade 316 stainless steel, the melting range of 316 SS is 2,500 F 2,550 F (1,371 C 1,399 C), roughly 50 to 100 degrees Fahrenheit lower than the melting point of grade 304 stainless.
AISI 304 stainless steel is the most commonly used material in stainless steels, and is usually purchased in an annealed or cold worked state. Because SS 304 contains 18% chromium (Cr) and 8% nickel (Ni), it is also known as 18/8 stainless steel.
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.
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.
316 SS offers good strength and creep resistance andalso possesses excellent me chanical and corrosionresistance propert- ies at sub-zero temperatures. 316L is a low-carbon modification of 316. The control of the n to a maximum of 0.03% minimizcarbo es the problem of carbide precipitation during welding and permits the use of the steel in the as-
At 26C austenitic stainless steel has tensile and yield strengths that are 172 MPa greater than the corresponding strengths for type 304 stainless. At -100C its tensile and yield strength exceed those of type 304 by 550 MPa and 276 MPa respectively.
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.
The PREN of Type 316 and 316L (24.2) is better than that of Type 304 (PREN=19.0), reflecting the better pitting resistance which Type 316 (or 316L) offers due to its Mo content. Type 304 stainless steel is considered to resist pitting and crevice corrosion in waters containing up to about 100 ppm chloride.
Ferritic, martensitic and duplex stainless steels tend to become brittle as the temperature is reduced, in a similar way to other ferritic / martensitic steels. The austenitics stainless steels such as 304 (1.4301) and 316 (1.4401) are however 'tough' at cryogenic temperatures and can be classed a 'cryogenic steels'.
Can I use stainless steel at low temperatures? 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.
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.
The alloy resists oxidation to 1500F (816C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness. Alloy 321H (UNS S 32109) stainless steel plate is the higher carbon (0.04 - 0.10) version of the alloy.
Type 304 stainless steel is a T 300 Series Stainless Steel austenitic. It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. It is defined as a Chromium-Nickel austenitic alloy. Grade 304 is the standard "18/8" stainless that you will probably see in your pans and cookery tools.

At low temperature, it can be that the of enthalpiessolid materials, such asseen G10 (which is a thermal insulator made of epoxy resin and glass fibres) and stainless steel AISI 304EN 10088L ( - 1&2 / 1.4306) for example, aremuch smaller than ose of gasesand especially than that of heliumth .A
316L is the low carbon version of 316 stainless steel. Covered in thsi document are the physical and mechanical properties of 316L stainless steel. Other areas such as heat treatment, welding, machining, hot and cold working, hardening, work hardening and applications are also outlined.
Type 321 stainless steel s also advantageous for high temperature service because of its good mechanical properties. Type 321 stainless steel offers higher creep and stress rupture properties than Type 304 and, particularly, Type 304L which might also be considered for exposures where sensitization and intergranular corrosion are concerns.
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.

Abstract. The most often used stainless steel grades for cryogenic applications are the AISI grades 304, 304L, 316, 316L and 316LN. Sometimes the grades 316Ti and 321 were used for low temperature service, however the recent studies show their rather limited applicability.
Building on SS wire, here's my second build It's 28g 316 ss, 6 or 7 wraps, 0.6ohm. A cloud machine, compared to anything I had in the past :) Now, for the sake of an experiment, I did some watt test on this wire, and seems that 100+ watts tend to ruin it to the point, where TC doesn't work correctly anymore - the resistance gets completely off buy ss 304 low temperature limit
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.
Types 304 and 304L are the most versatile and widely used of all the stainless steels. Their chemical composition, mechanical properties, weldability and corrosion/oxidation resistance provides the best all-round performance at relatively lower cost. These have excellent low-temperature properties and respond well to hardening by cold working.
