what is YK30 tool steel ? Applications and heat treatment of YK30 steel

YK30 steel is an oil-quenched carbon tool steel, often used in stamping dies, fixtures, gauges, paper knives, auxiliary tools, etc. Characteristic Vacuum degassing refined steel with stable quality; Good hardenability, oil-cooled hardening (less quenching and deformation); Good toughness and wear resistance, durable tools; YK30 adds Mn and Cr on the basis of SK105 to improve […]

How are seamless steel pipes produced?

How are seamless steel pipes produced? The production process of seamless steel pipes is mainly divided into two types: cold-drawn and hot-rolled. The production process of cold-rolled seamless steel pipes is more complicated than that of hot-rolled steel pipes. The pipe billet must firstly be under three-roll continuous rolling, and then sizing test after extrusion. If […]

Two important factors that affect welding of steel and aluminum

Steel and aluminum have different chemical and physical properties, such as melting point, thermal expansion coefficient, elastic modulus, etc. When welding steel and aluminum by hot working welding process, they will face many problems, that is, aluminum and steel are prone to form very hard and brittle IMP phases (Intermetallic phase), the greater the welding […]
