1 PCS 440c Stainless Steel Raw Material 9cr18 MO T10 D2 Die steel Quenched 440c Knife Blade Steel Billet

Please ignore the color, the product is stainless steel natural color

Characteristic:

High hardness and good wear resistance. When grinding, its disadvantage is that it is relatively viscous and heats up quickly, but it is easier to sand than any carbon steel, and it is much easier to cut with a hand saw. The annealing temperature of 440c is very low, and the hardness usually reaches HRC56--58. It has strong corrosion resistance and toughness. It is now widely used in hand-made knives and high-quality factory-made tools.

Application

After 440C, the hardness is high, the corrosion resistance is good (with magnetic) tableware (knife), and the turbine blades are hardened, and the hardness is higher than that of 440 steel (magnetic) blade, nozzle, valve, ruler, tableware (scissors).

Chemical composition(%):

C :1.10 Mn :1.00 P :0.03 S :0.010 Cr :17 50 Mo :0. 60 Ni :0.60 Cu :0. 50 Si :1.00

Feature application:

The 440C has the highest hardness of all stainless steel and heat resistant steel. For nozzles, shafts        Cheng. 440F: It is a steel grade that improves the easy cutting performance of 440C steel. For automatic lathes,        Martensitic stainless steels and common alloy steels have the property of hardening by fire, so a wide range of different mechanical properties can be obtained by selecting the grades and heat treatment conditions.
