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:Can I use steel bar instead of steel bar?
- The substitution principle of steel bars is equal section substitution and equal strength substitution. Therefore, we can not use round steel instead of thread steel.
- Q:What's the difference between bar and round bar?
- Bars can be either round or square or six sides.Another argument is that bars usually refer to short ones. The rounds are not cut, usually 6 meters long supply.
- Q:Specifications of the same kind of galvanized round bar more expensive than round steel?
- The general market price than ordinary steel galvanized steel bar of your 2000-3000 dollars per ton, according to your purchase requirements, price range of relatively large fluctuations, such as whether to open a formal invoice, transport distance, purchase quantity, relationship with your level of economic development, the developed area of fierce market competition, the price is relatively low. The prices and prices of large factories and small factories are not the same. The prices of big factories are generally high, and the prices of small factories are low.
- Q:Which is stronger, steel pipe or round steel? Which is good at bending?
- Of resistance to shearing, of course, of high round steel, generally used with steel tubes (light weight and material saving) for transmitting torque
- Q:Weight algorithm of round steel
- 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. Where: 5.5-25 mm small round steel mostly straight bundles of supply, used for steel, bolts and various mechanical parts; greater than 25 mm round steel, seamless steel pipe is mainly used for the manufacture of mechanical parts of the tube, etc..
- Q:What are square steel, rectangular tube, angle steel or light steel?
- Light steel is also a relatively vague term, generally can have two kinds of understanding. One is the current "code for design of steel structures" (GBJ 17-88) in the eleventh chapter "bar, small angle light steel structure", refers to the use of steel and light steel structure is less than L45*4 and L56*36*4 angle steel production, mainly in the lack of time for small steel structure manufacturing of reinforced concrete structure should not be used, has been basically not used, so the revised code for design of steel structures has been basically removed this tendency. The other is the "Regulations" technology of steel structure of light-weight buildings with gabled frames with light roof and wall light (also has the condition to use the masonry wall) single portal frame structure, the light here mainly refers to the enclosure is made of light material. Since the former has been cancelled soon, the meaning of "light steel" mainly refers to the latter
- Q:What kind of material is the first round steel?
- Standard Specification for hot rolled round steel is 5.5-250 mm. Where: 5.5-25 mm small round steel mostly straight bundles of supply, used for steel, bolts and various mechanical parts; greater than 25 mm round steel, seamless steel pipe is mainly used for the manufacture of mechanical parts of the tube, etc..
- Q:Why is the round bar bent?
- Gripping force: generally expressed by the strength of the concrete.Physical quantity of reinforced concrete to resist sliding ability, its sliding force divided by the holding area to express (Mpa), under normal circumstances, the bond strength is along the steel and concrete interface shear stress, which is the bond stress.
- Q:What kind of steel pipe is round steel?
- First of all, this is the two concept, round steel solid, hollow steel pipe; secondly, the round bar is divided into hot rolling, forging and cold drawn three. Generally seamless steel pipe can be divided into hot rolling (extrusion), cold rolling (pull), heat expansion of the basic types of steel pipe. Hope to be of help to you
- Q:What is the difference between steel and flat steel, round steel and steel?
- In fact, for the processing of raw materials are the same, is used when the roller rolling pressure is not the same, there are many different types of tooth roller shaft, can produce different steel, the steel section is square, round cross section is round
