Features of normalised fine grain steels ISO/TR 15608 material group 1.3
Non-alloy steels or 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 Carbon: C ≤ 0,25%
Specified yield strength: ReH > 360 N/mm2
Delivery condition: Normalised
Applications of normalised fine grain steels ISO/TR 15608 material group 1.3
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 carbon steels with specified ReH ≤ 275 N/mm2: see Group 1.1
For unalloyed carbon steels with specified 275 < ReH ≤ 360 N/mm2: see Group 1.2

FAQs to ISO/TR 15608 Material Group 1.3
Unalloyed carbon steels with a specific minimum yield strength ReH > 360 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.
