Adequate Supply Various Specifications Skt4 Steel Pipes Export - China

SKT4 steel pipes is a Japanese standard steel grade, a typical general steel for cold and hot molds.

The steel's hardenability, tempering resistance, wear resistance, and compression resistance are all the best among chromium-tungsten-silicon impact-resistant tool steels.

However, large and medium-section steels tend to have banded carbide segregation, so their toughness is poor.

The steel has the best hardenability and hardenability, so the mold has the best wear resistance and compression resistance.

The steel is highly sensitive to decarburization when heated, and it is difficult to control quenching deformation.

Heat treatment specifications for SKT4 steel pipes

① Hot working specifications Initial forging temperature 1050℃, final forging temperature>850℃.




② Ordinary annealing specifications Temperature 740~800℃, time 2~4h, slow cooling to a temperature of about 500℃, air cooling after furnace removal, hardness <241HBS after annealing.

③Quenching and tempering specifications: Quenching temperature 860~900℃, tempering temperature in oil 200~250℃, hardness 53~56HRC, tempering temperature 430~470℃, hardness 40~45HRC.
