It has excellent weldability,good machinability ,and high ductility with Brinell hardness of 119 - 235 and tensile strength of 410-790 MPa.
Mar 11, 2019 · Cold forging is a lot like hot forging except it is at or near room temperature. The lower temperature means that the steel is much stronger and it is much more difficult to forge. That also means the steel is more brittle and therefore more likely to crack during forging or rolling. The shape of the grains in the steel are changed through forging.

Being the topclass products in China, our products have been used in all kinds of areas, such as aerospace, electronic information, machine
Die Steel - Finkl SteelElevated levels of copper generate lubricity during the forging operation allowing for reduced levels of graphite. DURODI® 1.2714 mod:DURODI is suitable for closed die forging hammers, mechanical and hydraulic forging presses. The material hardens deeply and uniformly to a high hardness that holds up exceedingly well under impact and thermal
Cold forging has played a critical role in fasteners and has been applied to the automobile industry, construction industry, aerospace industry, and living products so that cold forging presents the opportunities for manufacturing more products. By using computer simulation, this study attempts to analyze the process of creating machine parts, such as hexagonal nuts.
Forging Glossary All Metals & Forge GroupCold coined forging A forging that has been restruck cold in order to hold closer face distance tolerances, sharpen corners or outlines, reduce section thickness, flatten some particular surface, or, in on-heat-treatable alloys, increase hardness.
Forging Knowledge from QC Forge Industrial ForgingsForging is the method that produces wrought properties. Often, the comparisons to wrought properties are made versus standard textbook values that were established as long as 100 years ago. Just as the new material processes have advanced, so forging has also advanced, improving metallurgical performance to meet the challenges
Oct 05, 2020 · The hot-forging process itself did not show any extraordinary behavior apart from a somewhat elevated hot flow stress due to chromium and molybdenum alloying, which serve as solid-solution strengthening elements. After air cooling, the component showed a homogenous distribution of hardness (Fig. 4). The hardness was found to be at 47 HRC.
GB 20 carbon seamless steel pipe ASTM A234 butt weld GB 20# carbon steel bar for steel pipe ,flange and pipe fittings. This group of Chinese (GB) standard specifications covers carbon and alloy steel plates and forgings used in boilers and pressure vessels, high-strength low-alloy steels, heat-treatable steels, hot and cold-rolled plates for cold forming, steels for concrete reinforcement and prestressed concrete and the properties for railway

Introduction To Heat Treatment Process in Forging This increases the strength and hardness. This process is performed on forging components that are to be machined as normalising improves the machinability of forged components. Stress Relieving Forging, rolling, cold working, non-uniform cooling cause internal stresses in a metal. To remove or reduce these internal stresses created in a

Scot Forge Subsea Steel Applications for Oil & GasSteel Forgings Used for Subsea Oil & Gas. Scot Forge recently exhibited at the 2018 Global Petroleum Show from June 12 - 14 in Calgary. Much of our discussions centered around material requirements for subsea oil & gas forgings.
Steel Forging & Tempering Chart Jantz SupplyThe forging process involved molding the knife at a critically high heat level (typically 900 - 2,000 degrees Fahrenheit) to improve its hardness. Once you are done forging the knife you can move on to the tempering process in which you increase the knife's flexibility and sharpness at a lower temperature, typically between 390 - 800 degrees
Difference between galvanized pipe and seamless pipe. Uses difference Seamless steel pipe is very widely used, except for water, gas, oil, general low pressure fluid line pipe, also used as heating oil oil industry in particular, marine oil field oil well pipes, pipelines, chemical coking equipment, a condensate cooler, coal distillation of wash oil exchange Used pipe, and trestle piles, mine
