Applications

YG6

Good hardness and normal strength, for drawing of steel and non-ferrous metal and alloy bars or tubes under the condition of higher Stress.

YG6X

High wear resistance and high hardness,for drawing of steel wires and non-ferrous metal wires or alloy bars under low-stress condition.

YG8

High wear resistance and high hardness,for drawing and straightening steels,non-ferrous metal and alloy bars and tubes; And for fabricating of machine parts,tools and wear parts,such as nozzles,centres,guiding devices,upsetting dies and perforating tools.

YG8X

Good strength and impact toughness; suitable for plates,bars,saws,seal rings,tubes etc. And it is one of the most popular grade for wear parts.

YG15

High Strength and impact toughness, but lower hardness and wear resistance.For drawing steel rools and pipes under high stress condition;And also for upsetting dies and perforating tools under higher impact loading.

YG20

Used as wear parts,sheets and some mechanical components.

ZK10UF

Fine-grained alloy, good wear resistance and high strength.It is one of the most popular grade for rods,bars,tubes and other wear parts, which need high wear resistance and good cautery resistance and low impact toughness.

ZK30UF

Fine grain grade. Excellent wear resistance, high in strength and impact resistance. Suitable for rough machining of cast iron,non-ferrous metals,nonmetallic materials and heavy cutting.

YG6N

Good wear resistance and cautery resistance, high strength and fine impact toughness. Suitable for the submarine oil pump parts such as bushes and sleeves with excellent impact toughness.
