Abstract:In this paper, the properties of the base metal of the low-alloy high-strength steel 20MnTiB, the welding process and the microstructure and properties of the welded joints were studied. The results are as follows:post-heat treatment below 400°C, the strength change of the steel decreases slowly, the elongation does not change significantly, and the metallographic structure is not obvious.

EN 1.7227 (42CrMoS4) Chromium-Molybdenum Steel

May 30, 2020 · EN 1.7227 steel is an alloy steel formulated for primary forming into wrought products. 1.7227 is the EN numeric designation for this material. 42CrMoS4 is the EN chemical designation. The properties of EN 1.7227 steel include three common variations. This page shows summary ranges across all of them. Failure analysis on 20MnTiB steel high-strength bolts in Dec 01, 2020 · Based on the statistical analysis results of the timespace distribution of 57 high-strength bolts of 20MnTiB steel with detached fractures found in a bridge , and the preliminary analysis of macroscopic and chemical properties of 13 fracture samples collected among these 57 failed bolts, three representative samples were selected in recent 5 years. #D1 has served for 4 years and is Microstructure and Mechanical Properties of Spot Welding The chemical composition and mechanical properties of base metals are shown in Tables 1 and 2 [18, 19]. A three-layer structure consisting of B1500HS steel with the thickness of 1.2 and 1.6 mm and

Modeling and Composition Design of Low-Alloy Steels

Accurately improving the mechanical properties of low-alloy steel by changing the alloying elements and heat treatment processes is of interest. There is a mutual relationship between the mechanical properties and process components, and the mechanism for this relationship is complicated.
