Temperature Tolerances for Grade 330 Stainless Steel Unlike the previous two stainless steel alloys, grade 330 stainless is frequently specifically marketed as a high temperature resistant alloy. As noted on the Penn Stainless website , grade 330 alloy has great oxidation resistance and resists scale formation up to about 2000 ° F due to STAINLESS STEELThe maximum temperature to which Type 304 can be exposed continuously without appreciable scaling is about 1650 °F (899 °C). For intermittent cyclic exposure, the maximum exposure temperature is about 1500 °F (816 °C). HEAT TREATMENTS Type 304 is non hardenable by heat treatment.Tempering of SteelStages and Classification Heat Medium Temperature Tempering (350 C to 500°C)This range of tempering produces troostile microstructure indicating development of high elastic limit with good toughness and hardness in
ASTM's temperature measurement standards provide the material and property specifications, as well as guides for the testing, calibration, and use of laboratory, industrial, and clinical instruments used in the determination of thermal variables, particularly temperature. These include thermoelement materials, hydrometers, liquid in glass Stainless Steel Type 304 304L Tempered & Specialty Type 304 (S30400), Type 304L (S30403) Description. Type 304/304L is the modern version of 18 8 stainless steel containing approximately 18% chromium and 8% nickel and is the most commonly specified stainless steel used throughout the world.AISI 304 Stainless SteelSpecification and Datasheet The SAE/ANSI 304 (AISI 304) is the most commonly available and used type of stainless steel.It is also referred to as 18/8 stainless steel, A2 stainless steel (as per the ISO 3506), or 304S15 (as per the British Standard).This is an austenitic chromium nickel alloy which practically means that it has a very high corrosion resistance.

Carburized specimens were heat treated by heating to 760°C, water quenched to room temperature, then tempered at temperatures 200°C, 300°C and 400°C for one hour to relieve the internal stresses that have been set up afterSAE AISI 4340 Steel Properties, Heat Treatment, Equivalent TemperingHold at 200 to 650 °C (400 to 1200 °F) for at least 1/2 hour; air cooling. The temperature and the time at the temperature mainly depend on the required final hardness. Stress ReliefAfter straightening, forming or processing, the stress of the part can be released at a temperature of 650 to 675 °C (1200 to 1250 °F).

TABLE 1 Chemical Requirements (Heat Analysis) Element Composition, % Carbon, max 0.55Heat Treating Aluminum AZoMFor naturally aged alloys, this happens at room temperatures and takes four or five days to reach full strength, but 90% of the hardening happens in the first 24 hours. The process starts immediately after the quench, but because it is a slow process there is a window to shape the alloy with relative ease immediately after quenching.4140HW Alloy Steel Technical Data60 minutes at temper temperature.
