ISO/TR 15608 Material Group 1.1 e.g. P265GH: Unalloyed Low carbon steel with a specific minimum yield strength ReH ≤ 275 N/mm2 a and with follow analysis:
C ≤ 0,25%; Si ≤ 0,60%; Mn ≤ 1,8%; Mo ≤ 0,70%b; S ≤ 0,045%; P ≤ 0,045%; Cu ≤ 0,40%b; Ni ≤ 0,5%b; Cr ≤ 0,3%b; (0,4% for castings; Nb ≤0,06%; V ≤ 0,1%b; Ti ≤0,05%;
Remarks:
a In accordance with the specification of steel product standards, ReH may be replaced by Rp0,2 or Rt0,5;
b A higher value is accepted, provided Cr+Mo+Ni+Cu+V ≤ 0,75%
Features of unalloyed low carbon steel such as P265GH
Unalloyed Low carbon steels are those that contain other alloying elements such as manganese, chromium, nickel, vanadium, or titanium in smaller quantities. In terms of quality, they can be with special characteristics in terms of toughness, grain size, formability, yield strength, ductility, cold formability and weldability.
Specified yield strength ReH ≤ 275 N/mm2
Applications of unalloyed low carbon steel such as P265GH
Due to the moderate carbon content and the specified low alloy constituents, the steels in this material group are suitable for application temperatures up to approx. 300 °C. These steels also have specified strength characteristics such as yield strength or tensile strength. These characteristics make this material group essential in the manufacture of parts and machinery, pressure equipments for the chemical industry, the oil industry and other industries, among others.
For Unalloyed Low carbon steel with specified 275 < ReH ≤ 360 N/mm2: see Group 1.2
For Unalloyed Low carbon steel with specified ReH > 360 N/mm2: see Group 1.3

FAQs to ISO/TR 15608 Material Group 1.1
Low carbon steels with a specific minimum yield strength ReH ≤ 275 N/mm2 and specific analysis.
The material groups according to ISO/TR 15608 are primarily classified for welding purposes, but can also be used for other purposes such as heat treatment, forming and non-destructive testing.
Classification is usually based on chemical product analysis and/or mechanical material properties.
This standard covers steels, aluminium and aluminium alloys, copper and copper alloys, nickel and nickel alloys, titanium and titanium alloys, zirconium and zirconium alloys and cast irons.
No, it is similar but not exactly the same.
