EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of GB/T 3077 test. The standard covers the following topics of hot rolled and forged alloy steel: size, shape, weight, tolerance, engineering properties, test method, inspection rules, packaging, marking and quality certificates.
The standard applies to alloy structural steel bar with a maximum diameter or thickness of 250 mm. Bar stock larger than 250 mm in diameter can also be provided after consultation between the two sides of supply and demand. The chemical compositions of steel grades specified in the standard are also valid for steel ingots, billets and their manufacturing.
The standard provides a classification and identification system for different types of alloy structural steels according to their chemical composition and mechanical properties. GB/T 3077 specifies the permissible chemical composition ranges for various alloying elements such as carbon(C), silicon(Si), manganese(Mn), phosphorus(P), sulfur(S), chromium(Cr), nickel.
The standard outlines the mechanical properties that alloy structural steels must meet, including tensile strength, yield strength, elongation, area reduction, and hardness requirements.
Provides guidance on heat treatment processes for alloy structural steels, including annealing, quenching, tempering and other heat treatment methods. GB/T 3077 defines procedures and requirements for the inspection and testing of alloy structural steels, including methods of sampling, chemical analysis and mechanical testing.
