1. cold work mould/die steel
2. High carbon high chromium type ledeburite
3. High hardness wear resistance
1. Cr12 steel is a widely used cold work die steel, a type of high carbon high chromium ledeburite . The steel has good hardenability and good abrasion resistance
2. Mainly used to with stand the impact load is smaller, and require high abrasion resistance Die and punch, cold-cut scissors, drill sets, gauges, drawing die, pressure die thread rolling board, drawing die thread rolling die.

We are professional manufacture of tool steel. We can provide various kinds of tool steel and mould steel. If you have any question regarding our products ,please feel free to let us know. We assure you will receive our best attention to your enquiry.
- Q:Three - grade thread Phi 10 steel can replace a grade Phi 12 round bar? Which elder knows, trouble pointing.
- Notes on reinforcement replacement1, steel replacement, to understand the design intent, the important components of the steel replacement, with the consent of the design unit (the actual: to change the design units should be agreed).2, steel replacement, should meet the minimum reinforcement ratio requirements and reinforcement structure (such as minimum steel reinforcement diameter, spacing, root number, anchorage length, etc.) provisions. The bar as possible with the original design of root number.3, crack resistance requirements of the components (such as crane beam, truss bottom chord, etc.) with smooth steel (not reinforced grade) instead of rebar.4, do not change the effective height of the component.
- Q:How is the copper wire and galvanized round steel connected during the construction of the lightning protection device?
- Generally, the lightning protection devices of buildings are divided into two major categories: external lightning protection devices and internal lightning protection devices. The external lightning protection device consists of a lightning receiver, a lead off line and a grounding device, namely the traditional lightning protection device. Internal lightning protection device is mainly used to reduce the lightning current inside the building and electromagnetic effects, such as the use of electromagnetic shielding, equipotential connection and installation of surge protection device (SPD) and other measures to prevent the harm caused by lightning electromagnetic pulse.
- Q:Are steel and round steel the same thing?
- Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed in diameter, in units of millimeters (mm), such as "50mm", which means a diameter of 50 millimeters of round steel.
- Q:Difference between round bar and other steel bars
- Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter.
- Q:12mm Round steel, the material is Q235, the maximum weight can bear?
- Standard Specification for hot rolled round steel is 5.5-250 mm. Among them, 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
- Q:What kind of steel is used for anchor bolt material? What's the quality of anchor bolt material?
- When the mechanical component is installed on the concrete foundation, one end of the bolt is J and L shaped, and is embedded into the concrete.
- Q:Difference between forging and round steel
- The advantages of a casting include an extensible length, a contracted cross section, a contracted length, an extended cross section, a variable length, and a variable cross section. The types of casting are free forging / hand forging, hot die forging / precision forging, top forging, roll forging and die forging.Forgings are not limited to round shapes.Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter.Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of them: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
- Q:What kind of steel bars are used in general civil buildings?
- Steel is the HRB335, the diameter of 12 to 22, 25, 28, even 32, and then rough generally appear in the mass concrete construction, not commonly used, generally below 25 is commonly used in masonry structure in rural low level below 16 is most commonly used. Used as beams, columns, main bars and stand bars, etc.
- Q:Lightning protection earthing zinc plating flat iron and round steel welding method, need to flat iron wrapped in round steel outside welding?
- Unwanted。 The round bar shall be welded directly on flat steel, requiring both sides of the round bar to be welded, and the length of lap welding shall be 6 times of the diameter of round steel.
- Q:Do you need paint for roof lightning proof steel bars?
- The roof lightning protection round steel is the use of metal electrical conductivity and the principle of point discharge, the accumulation of the earth's electricity more rapidly spread to the air, play a role in lightning.
