Otai keeps the daily storage of the SCM440 plate. It is professional material for the N95 Mask machine ,because SCM440 has good properties.
2020 is a special year for everyone because of the pandemic. All people get into a panic .we hurry up to buy the masks, then someone busy buying the Ventilators. Others made an urgent request for the tissue. However, as a member of a steel company, we are busy keeping the storage of steel. The price of steel fluctuates. We will keep the daily storage of the SCM440 plate. It is professional material for the N95 Mask machine.
We sold many 42crmo4 plates, it is a hot-selling product of Otai company. To server the customer better, we bought new equipment for cutting steel. More sizes of SCM440 are available.
We had 20 year experience of 4140 plate trade and processing ,and had trade with middle east& sounth American countries.etc.we also offer milling and graiding processing,and most of the customer will take it for automobile die.we offer three condition.NO.1,hot rolled,black surface.NO.2.Q+T,No.3,Annealed.and the Q+T hardness would be 28-32 HRC generlly.
AISI SCM440 plate equivalent material
♦JAPAN♦ : JIS SCM440 alloy steel
♦GERMANY♦ : DIN WN-r 1.7255 / 42CrMo4 steel alloy
♦CHINA♦ : GB 42CrMo steel
♦BRITISH♦ : BS 708M40
SCM440 steel has good workability, slight processing deformation, fatigue resistance is quite good, is a medium and so on hardenable steel, SCM440 heat treatment has better strength and good comprehensive mechanical properties, good processability, yield High. The highest use temperature is 427 degrees Celsius. SCM440 strength, high hardenability, good toughness, small deformation during quenching, high creep strength and long-term strength at high temperature. It is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, heavily loaded connecting rods and spring clips. Petroleum deep well drills pipe joints and fishing tools below 2000m and can be used in the mold of the bending machine.
