9SiCr hot rolled steel round bars

9 sicr steel is low alloy cutting steel, but also often make cold work mould parts, the effect is very good. It than chrome steel (Cr2 or 9 Cr2) have higher hardenability and hardenability and have high tempering stability. The steel quotations from the former Soviet union as early as 9 xc, once known as 9 crsi steel. Composition and performance with 9 xc are exactly the same.

20MnCr5 hot rolled steel round bars

20MnCr5 steel is a low alloyed engineering case hardening steel for parts which require core tensile strength of 1000 – 1300 N/mm² and good wearing resistance. This steel is carburising steel used for components requiring high wear resistance surface, coupled with tough cores to resist shock loads and strength to give large service life.

18CrNiMo7-6 hot rolled steel round bars

18CrNiMo7-6 is a case hardening steel with high toughness. There are a number of variants with high cleanliness requirements. All variants possess tighter composition ranges compared to the standard. produced with the quality class IQ (isotropic quality). This ensures a very low number of elongated sulphide inclusions which will give more isotropic properties. The high oxidic cleanliness will enable the steel to meet the same high cleanliness demands as for re-melted qualities
