3Cr13 (oil quenched at 1000°C, tempered at 580°C) metallographic diagram
MARTENSITE STRUCTURE OF AISI 420/3CR13 STEEL
AISI 420/3CR13 steel is a martensitic stainless steel alloy. It contains 0.3-0.5 Carbon, 13-14.5% Chromium and other minor elements. Martensite is a type of microstructure that forms when a steel is heated to a temperature above the critical temperatur......
Fracture analysis of 42Mn2 steel (heated to 1200°C for forming)
Welding and Heat Treating Analysis of 40Mn2 Steel (Heated to 1200℃)
Welding is a technique that involves joining materials, such as metals and thermoplastics, through the application of heat or pressure. Welding is widely used in industries such as automotive manufacturing, aircraft production, ......
Leakage and Crack Analysis of Stainless Steel Weldment
Analysis of Stainless Steel Welding Joints Leakage Cracking
Abstract
Leakage cracking can occur in stainless steel welding joints under certain conditions. In order to reduce the occurrence of leakage cracking, it is necessary to pay attention to the selection of welding materials, welding param......
1Cr18Ni9Ti steel (solution treatment and stabilization treatment) non-metallic inclusions
Nonmetallic Inclusion in 1Cr18Ni9Ti Steel (Solution Treatment and Stabilization Treatment)
Nonmetallic inclusions (NMIs) are mineral or organic impurities that are unintentionally included in steel during production. It is well known that NMIs can have a detrimental effect on the properties of th......
