840 Stainless Steel Strip
840 Stainless Steel Strip Quick Details
Grade 840 stainless steel strip is a titanium and aluminum bearing austenitic stainless steel offering elevated-temperature scaling resistance superior to conventional chromium-nickel stainless steel strips, such as grade 304 strip.
The oxidation resistance of 840 alloy strip compares favorably with higher alloyed grades up to 1900ºF (1038ºC), making it a good candidate alloy for use in sheathing for electric heating elements, automotive emission control systems, and other applications where resistance to elevated temperature degradation is important.
840 alloy strips are slitted from mother coils.
At HZW, Our team can help provide round edge 840 strips to meet your special demands.

840 stainless steel strip application
- Hot Runner Heating Coils
- Heating Rods
- Heating Tubes
- Thermocouples
- Temperature Control Boxes
- Temperature Control Accessories And Connectors
What are 840 stainless steel strips edges?
Mill edge is a non-trimmed edge appearance after hot or cold rolling and annealing/pickling process. It usually leaved an irregular pinhole line on the edge side around 10mm to 15mm.
Slit/slitting edge means we will trim irregular pinhole line on our slitting machine.
In addition, our expert team can also provide round edge 840 strips to meet your project needs.
How to buy 840 stainless steel strip from China?
Therefore, if you want to buy 840 alloy Strip at lower price with high quality and good service from China suppliers, you need to know how to buy nickel alloy strips from China firstly.
First of all, you should choose a reliable supplier who can provide good quality 840 alloy coils products at competitive prices. Then you can negotiate with them on price and other terms until reaching an agreement.
Secondly, you need to check whether they have advanced production equipment or not because if they do not have advanced equipment for producing various kinds of coils including nickel alloys coils or if their production capacity is limited then it would be difficult for them to supply high quality products at competitive prices all year round.
Thirdly, it is better to visit their factory by yourself and check the production line and warehouse by yourself. It will be great if you can check their production process and production equipment. Because it is very important for you to know how they control the quality from process till delivery.
