AISI 5160 Spring Steel - NQA ISO certificated factory

AISI 5160 alloy steel has poor welding property owing to its high chromium and carbon content. Either arc or gas welding methods can be used to weld the steel. Heat Treatment. AISI 5160 alloy steel is generally hardened using oil. This steel is quenched at 829°C (1525°F) and tempered at temperatures ranging from 427 and 704°C (800 and 1300°F). China 45 Steel Equivalent, Mechanical Properties

  • China 45 SteelData Sheet & SpecificationProperties & ApplicationsEquivalent GradeChinese GB standard 45 steelis a quality carbon structural steel, the cold plasticity is common. Annealing and normalizing are slightly better than quenching and tempering, and have high strength and good machinability. A certain degree of toughness, plasticity and wear resistance can be obtained after appropriate heat treatment. Suitable for hydrogen welding and argon arc welding, not suitable for gas welding. Preheating is required before welding, and stress relief annealing should be performed after How to weld AISI 4140 Steel materialweldingAISI 4140 is high-strength medium carbon steel. 4140 can be easily welded with the right precautionary steps being applied. Other steels in this category as AISI 4130 and 4340 follow the same welding advice. This article provides a detailed introduction to the AISI 4140 materials, their properties, welding, and PWHT requirements.

Dissimilar joining of AISI 304/Q345 steels in keyhole Mar 17, 2018 · Weld microstructure is lath martensite and retained austenite. Proeutectoid ferrite and Widmanstatten structure are observed in Q345 heat-affected zone (HAZ) while no obvious grain growth is found in AISI 304 HAZ. Microhardness of the weld metal is much higher than the base metal because of the martensite structure in the weld.
