It hasbeen used for gas turbine compressor components such asblades,discs,rotors and shafts and similar parts where high strengthis required at intermediate elevated temperatures. Depending uponthe heat treatment, alloy 355 may have an austenitic structure andformability similar to other austenitic stainless steels or amartensitic structure and high strength coQuenching of Steel:Purpose and Mechanism Industries The action will continue with heat flowing from the centre of the workpiece to the surface until both the workpiece and the quenching medium attain the name temperature. The rate at which the heat can be abstracted from the steel is controlled by the thermal conductivity of steel and the specific heat of the quenching medium.
ASTM A36 Carbon Steel vs. SAE-AISI 1020 Steel May 30, 2020 · ASTM A36 Carbon Steel vs. SAE-AISI 1020 Steel. Both ASTM A36 carbon steel and SAE-AISI 1020 steel are iron alloys. Their average alloy composition is basically identical. There are 31 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.
Description. AISI 1030 is a high-carbon steel containing approximately 0.30% carbon that can be hardened by heat treatment to a maximum hardness of approximately Rockwell C 50. Soft annealed high carbon steel is intended for applications requiring moderate forming, while soft spheroidized annealed product is intended for applications requiring Consumables Corner:Before choosing filler, know your 4140Jun 24, 2014 · Finally, the proper filler metal can be a low-carbon E70XX or E80XX electrode with some nickel, or a stainless steel electrode such as E309. E70XX is the most cost-effective of the three choices; however, if the in-service conditions are subzero temperatures, you will want something that can handle cold temperatures, hence the nickel-based or stainless steel filler metals.

When forming, the HAZ can make it difficult to manage the bending angle because it becomes impossible to foresee how metal will behave after a heat-intensive cutting process. One of the affected behaviors is springback.
