Heat to 1300 oC maximum, hold until temperature is uniform throughout the section and commence forging.Do not forge below 950 oC Finished forgings may be air cooled. Heat Treatment Annealing Heat to 890 oC - 920 C hold until temperature is uniform throughout the section, and cool in furnace. Carburizing Pack, salt or gas carburise at 900 oC holding for sufficient time to develop the required ASME SA-336 Grade F321 ASME SA-336/SA-336M - BBN ASME SA-336 Grade F321 ASME SA-336/SA-336M is one of the main products of our company. Other than offer high quality SA-336 Grade F321 with competitive price, we also help to resolve all kinds of doubts of clients. Such as SA-336 Grade F321 chemical composition, SA-336 Grade F321 properties,SA-336 Grade F321 yield strength, SA-336 Grade F321
As a corten steel product manufacturer and exporter in China, BBN steel has large stock of weather resistant steel grades A242 Type 1, Corten A plate, A588 Grade A, S355J2W hot rolled sheet, 09CuPCrNi-A, EN 10025-5 steel, S355J2W, S355J0WP,Q355NH, SPA-H weathering steel, SPA-C Effect of post weld heat treatment soaking time on The thermal efficiency of High-Pressure Boiler Plants (HPBP) is intensely depends on steam temperature and pressure. So it is essential to develop such advanced material which can withstand steam temperature of 500 - 600°C and pressure of 180 - 300 bar . In order to suit this requirement, advanced materials should have Flange Ratings and Flange Classes for ASME FlangesFrom the above table, you can see that a 150 lb carbon steel flange, the allowable pressure is 285 psi at 100°F, 170 psi at 500°F, and 20 psi at 1000°F. The only temperature at which the flange is rated for 150 psi is near 500°F. Higher class flanges are rated at their nominal pressure rating only at near 850°F. See the cells in yellows.
5) Under the highest working temperature and self-load, the oxidation resistance is good, and it can withstand high temperature creep and damage strength; 6) Small thermal expansion coefficient Heat exchanger made of superalloy Cr25Ni20 series, popularly Jis B2220 - Flanges 5k & 10k, Jis B2220 2k & 16k Flange Jis B2220 Flange Material used by manufacturers to produce these flanges includes metals like stainless steel, carbon steel, alloy steel & nickel alloys. The material used to make these ANSI B16.5 5K (KS B1503 / JIS B2220)Flanges will depend on its application or end use. For e.g. - Stainless Steel 10K JIS B2220 Flanges will be used in those MECHANICAL PROPERTIES OF CARBON STAINLESS STEELC.

Nitronic 60 is truly an all purpose metal. This fully austenitic alloy was originally designed as a temperature alloy, and subsequently has good high temperature properties for temperatures around 1800ºF. The oxidation resistance of Nitronic 60 is similar to Type 309 S.S., and far superior to Type 304S.S. This grade is best known for its wear Plate Corten SPA-H JIS G3125 Steel PropertiesFor unprotected use care must be taken that the welded joint is also weather resistant. This is possible by using welding consumables matching the base material. If due to design or building specification stress relieving is required, it should be performed in the range temperature from about 530°C to 580°C. SPOT WELDING TECHNICAL INFORMATION - Tite-Spot Welding current and time are used to bring the metal to welding temperature (2550 Degree F.). Weld Temperature = i 2 x t x R. Welding current in a body shop environment has a range of 3000 to 5000 amperes. Welding current ( i ) and weld time (t) are to be controlled by the technician. Resistance (R) is determined by the gauge of the parts being
proximately 10% lower than that of JIS SUS 310S, an austenitic stainless steel, it demonstrates superior high-temperature strength and oxidation resistance. It is used as a substitute for SUS 310S for high-temperature applications at various power plant facilities and industrial furnaces. It is used also for automotive exhaust systems.STEEL PLATESC SMA 490 JIS G 3101Rolled Steel for General Structures SS330, 400, 490, 540 JIS G 3136Rolled Steel for Building Structures SN 400A, 400B, 400C, 490B, 490C JIS G 3106Rolled Steel for Welded Structures SM570 JIS G 3128690 N/mm2-Class High Yield-Point Plate for Welded Structures
