Why the 4140 plate for mask machine ultrasonic is necessary?

42CD4 Plate Q+T

Why the 4140 plate for mask machine ultrasonic is necessary?

Since the coronavirus is under control,we start business,like I said before,the 4140 plate is sold a lot and very quickly,as the 4140 plate for mask machine ultrasonic,to produce medical ear-loop face masks with nonwoven materials.

I discussed an 4140 plate order of 175 tons,it just discuss 1 days ago,and my customer sign the contract and make a payment,however,when the payment is reach,I intend to arrange shipment,the warehouse told me that all thickness of thickness 35-40-45mm are sold out,a factory who produce mask machine ultrasonic need it urgently,we know the market demand a lot of mask,but now,the situation is demand exceed supply,every one are waiting more mask in market.it need more factory to manufacture face mask,but the factory need more machine increase the productivity,so now,most of the factory ask for the 4140 plate 35-40-45mm,and some of them had pay already,but these specification is scarcity.

Now,let’s check the most popular steel in 2020 as below.

Applications

DIN 4140 Tool steel is a alloy structural steel, 4140 is used for engineering structural, like high tensile shafts, bolts and nuts, gears, pinions and spindles. Locomotive traction with the big gear, supercharger drive gear, pressure vessel, rear axle, gear load of connecting rod and a spring clip,4140 can also be used to under 2000 m deep well of oil drill pipe joint and the fishing tool, and can be used for bending machine mould, etc

Forming

AISI 4140 alloy steel has high ductility. It can be formed using conventional techniques in the annealed condition. It requires more pressure or force for forming because it is tougher than plain carbon steels.

Welding
AISI 4140 alloy steel can be welded using all conventional techniques. However, the mechanical properties of this steel will be affected if it is welded in the heat treated condition, and post weld heat treatment should be performed.
