There are many types of die steel, and different die steels have different uses and methods of use. The specific knowledge is introduced below for you:

Many plastic mold manufacturers are interested in good surface roughness; when sulfur is added to improve metal cutting performance, the surface quality will decrease as a result, and steel with high sulfur content will become more brittle.

CRl2

crl2 performance: high carbon, high chromium type ledeburite steel, with good hardenability and good wear resistance. Because the carbon content of steel can reach 2.30%, the steel becomes hard and brittle, so the toughness of Chongnan is poor, it can hardly withstand large impact loads, it is easy to brittle, and it is easy to form uneven eutectic carbides. .

Uses: Used to manufacture cold punches and punches that are subject to less impact load and require high wear resistance, cold cutting blades for cutting hard and thin metals, drill sleeves, gauges, drawing dies, stamping dies, rubbing Wire plate, drawing die and screw rolling die, etc.

Production varieties: hot-rolled materials, cold-drawn materials, forging materials, hot-rolled steel plates, and cold-drawn steel wires.

CRl2MO1V1

Performance: high carbon, high chromium type ledeburite steel, drilling is not an essential element when there is no special requirement. Because the content of molybdenum and vanadium is higher than crl2mov, the structure and grain size of the steel are further refined, the hardenability, strength and toughness of the steel are improved, and the comprehensive performance of the steel is better.

Uses: Used to manufacture large and complex cold work molds that require high wear resistance, such as cold cutting scissors, trimming dies, wire drawing dies, thread rolling dies, thread rolling dies, hemming dies, and cold punching dies and punches that require high wear resistance, etc. .

Production varieties: hot-rolled materials, forging materials, cold-drawn materials, hot-rolled steel plates, and cold-drawn steel wires.

CRl2MOV

Performance: High-carbon, high-chromium ledeburite steel, with good hardenability, can be completely hardened with a cross-sectional size below 400mm, has high wear resistance, and has small volume changes during quenching. Its carbon content is much lower than crl2 steel, and molybdenum and vanadium are added. Therefore, the hot workability, impact toughness and carbide distribution of steel have been significantly improved.

Uses: Used to manufacture cold work molds with large cross-sections, complex shapes, high wear resistance requirements, and large impact loads, such as cold cutting scissors, trimming dies, hemming dies, gauges, wire drawing dies, thread rolling boards, and threads Rolling dies, punching dies with complex shapes, deep drawing dies for steel plates, and cold punching dies and punches that require high wear resistance.

Production varieties: hot-rolled materials, forging materials, cold-drawn materials, hot-rolled steel plates, and cold-drawn steel wires.

CR5MOLV

Performance: The alloy content is medium. Because it contains molybdenum and vanadium, the steel has good hardenability, uniform carbide distribution, certain impact toughness and good wear resistance.

Uses: used to manufacture shaping dies, drill sleeves, cold punch dies, punches, trimming dies, thread rolling dies, thread rolling boards, gauges, etc.

Production varieties: hot-rolled materials, forging materials, cold-drawn materials, hot-rolled steel plates, and cold-drawn steel wires.

9MN2V

Performance: Compared with carbon tool steel, the comprehensive mechanical properties have higher hardness and wear resistance, good hardenability, and less deformation during quenching. Because the steel contains a certain amount of vanadium, the crystal grains are refined and the overheating sensitivity is reduced. The carbide unevenness is better than crwmn steel.

Uses: Used to manufacture various precision measuring tools, templates, and generally required smaller dies, cold press dies, engraving dies, material dies, scissors, taps, dies and reamers, etc.

Production varieties: hot-rolled materials, forging materials, cold-drawn materials, hot-rolled steel plates, and cold-drawn steel wires.

Small and medium-sized modules can be supplied according to the requirements of the buyer.

CRWMN

Performance: It has high hardenability. Because 1.20%~1.60% (mass fraction) of tungsten is added to form carbides, it has certain hardness and wear resistance after quenching and low temperature tempering. Tungsten helps to maintain fine grains, so that the steel has better toughness, the steel is more sensitive to the formation of carbon nets, and this kind of carbon public net makes the tool edge part of the risk of spalling.

Purpose: Use a wide range of cold work die steel. Used to manufacture measuring tools, such as die, block gauge, sample column and sample sleeve, and high-precision dies with complex shapes.

Production varieties: hot-rolled materials, forging materials, cold-drawn materials, cold-drawn steel wires, silver-bright steel wires, hot-rolled steel sheets, and cold-rolled steel sheets.

9CRWMN

Performance: Low-alloy cold-work die steel, with certain hardenability and wear resistance, small quenching deformation, uniform carbide distribution and fine particles.

Uses: Used to manufacture cold stamping dies with small cross-sections and complex shapes, as well as measuring tools such as gauges and templates.

Production varieties: hot-rolled materials, forging materials, cold-drawn materials, cold-drawn steel wires, and cold-rolled steel plates.
