527A19 has high hardenability, no temper brittleness, very good weldability, little tendency to form cold cracks, and good machinability and cold strain plasticity. It is generally used in the quenching and tempering or carburizing and quenching state. It is used to manufacture high-pressure pipes various fasteners and higher-grade carburized pipes that work in non-corrosive media and media with operating temperatures below 250°C and containing nitrogen and hydrogen mixtures. Carbon parts such as gears, shafts, etc.

527A19 alloy steel properties and applications
527A19 contains an appropriate amount of alloying elements and the carbon content is about 0.2%. After carburization treatment, the surface has high hardness and the core also has excellent toughness. 527A19 Lost Wax Investment Castings are widely used in boiler and steam turbine manufacturing industries. Partitions, blades, forgings, profiled materials, high-pressure pipes, and various fasteners are made in the chemical industry, and higher-end carburized parts, such as gears and shafts, are made in the machinery manufacturing industry.
