Inconel 718 tube containing precipitation hardening type molybdenum alloy, niobium, so nickel-chromium below 650℃ high strength, good toughness, good corrosion resistance, high temperature, also and low-temperature environment.
The supply state can be a solution treatment or a precipitate-hardening state.
Features of Alloy 718:
1. End processability
2. High tensile, fatigue, creep, and fracture strength as low as 700 ° C
3. High oxidation as low as 1000℃
4. Both ends have stable low-temperature chemistry
5. Good welding performance
Applications and properties:
Manufacture of rings, blades, fasteners, and structural parts in aviation, aerospace, and petrochemical industry, and a variety of parts used in the petrochemical industry use the alloy 718.
We can mass-produce the alloy, and it has good performance.
1. Gas-fired turbine
2. Rocket engine engine
3. The spaceship
4. Nuclear reactors, pumps

PVC film is one of the most important factor when purchasing stainless steel material. Basically, 3 types of PVC films are typically applied.
PE50/PE80 black and white film
This is the most widely used film, the thickness normally ranges from 50 micron to 80 microns. There will not be any special function except protection.,
Laser Film(Novacel 4228)
Laser cutting is often applied as a downstream processing. Laser film is a film that can undertake high temperature. If clients apply the wrong pvc, after laser cutting, the pvc will be wrinkled and sticky to the surface.
There are normally 2 types of blue transparent film, one is the for deep drawing, another one is normal protection film.
Stainless Steel sheet/Plates Packing and Loading Solution
The edge part should be clean and slit, no residues left.
Back side kraft paper
To make sure there is less moisture going into the pallet, water proof kraft paper should be applied.
Standard sheet package
A layer of wooden plate will be put on the top of the pallet. And 3*2 steel strip will be applied.
Block and bundles
Wooden blocks and bundles will apply on the loading of the pallets.
If there are too many pallet in one column，the top part also need be strengthened.
Wooden box package
For stainless steel mirror sheet, we can also apply wooden box.
Normally, different mills will apply 3 types tolerance, like 1.0mm, there will be 0.91-0.92mm/0.94-0.96mm/ 0.98-1.01mm. 3 stages to apply for different application.
Width tolerance mainly depends on the slitting and cutting machine. We use Taiwan and Italy machinery, which can guarantee +/-0.05 to +/-0.1mm
Diagonal Tolerance is a key factor to show whether the cut is correct or not. The normal tolerance is +/-2mm。
