Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.
SAE4340, same as UNS G43400. Tensile strength σb ≥980(100) Yield strength σs ≥835(85), used to manufacture important parts with high strength and good plasticity. After nitriding treatment, make important parts with special functional requirements, such as shafts, gears, and gears. Firmware etc. Delivery A633 Grade A indian equivalent in heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment.
Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium A633 Grade A indian equivalent carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some A633 Grade A indian equivalent alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
A633 Grade A indian equivalent, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.
Booking space and making power of attorney (ten copies of order); the data of the original order shall be correct and consistent to the greatest extent when making the order, so as to reduce the frequent changes in the subsequent process.
