EN 10120 Grade HCT600XB introduction

Cold rolled continuously annealed dual-phase steel offers an outstanding combination of strength and drawability as a result of its microstructure, in which a hard martensitic phase is dispersed in a soft ferritic phase. This steel grade has a high strain-hardening capacity and high yield strength (Re), giving it a good strain-redistribution capacity, and thus good drawability.

As a result of strain-hardening, the mechanical properties of the cylinder after forming, especially its yield strength, are superior to those of the initial blank.

The fundamental property of this steel for gas cylinders is that it can withstand high pressure in different “in-use” conditions. To withstand high pressure, it is advantageous to have high strength, where specifically high-strength hardening during deep drawing permits a significant thickness reduction compared with the conventional hot rolled steels used for this application, with no impact on the usual processing steps.

Combined with good ductility at low temperatures, weldability, good fatigue and non-ageing properties (non-ageing meets the regulatory requirements outlined in EN 14638), it is the best choice of material to use for lightweight steel cylinders.
Furthermore, the environmental impact of these lightweight cylinders made of 100% recyclable steel from both manufacturing and use is significantly reduced compared with conventional steel cylinders, making them a very sustainable alternative.
