A2-70.
Corrosion resistance of stainless steels decreases with increasing
carbon content, so most stainless steels have a low carbon content
of up to 1.2% and some have a Wc (carbon content) of less than
0.03% (eg 00Cr12). The main alloying element in stainless steel is
Cr (chromium). Only when the Cr content reaches a certain value,
the steel has corrosion resistance. Therefore, the stainless steel
generally Cr (chromium) content of at least 10.5%. Stainless steel
also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements.
Stainless steel corrosion resistance decreases with the increase of
carbon content, therefore, most of the stainless steel carbon
content is low.
The spring washer has pretension, after compression, the rear
recoil. In actual use, because of the characteristics of the
thread, the nut is easy to rotate along the direction of the
spiral, causing the nut to loosen. In order to solve this problem,
the spring washer appeared. Spring washer with pretension, the nut
after compression spring washer, in under the action of tension, in
the triangle screw and bolt nut screw side, tightly to stick
together, in under the action of friction, loose nut will no longer
appear.
Spring washers are used for anti-loosening, flat washers have no
anti-loosening function, flat washers just increase the contact
area.

1. Internal tooth washer, external tooth washer
There are a lot of sharp, flexible thumbs on the circumference that
press against the bearing surface to stop the fastener from
loosening. Internal rubber washers are used under the heads of
smaller head size; external rubber washers are mostly used under
the head of bolts and nuts. The toothed elastic washer is smaller
in size than ordinary spring washers and has even force on the
fastener to prevent loosening and reliable, but should not be used
in the usual disassembly place.
2. Wave spring washer
Wave washers divided into WG type, WL type, WN type
3. Disc spring washer
Disc spring washer Belleville spring washer, also known as
Belleville French. HDS Series is a very effective bearing load and
elastic recovery. Bolt tension can withstand slack due to wear,
creep, relaxation, thermal expansion, shrinkage, or seal
compression of the consumable parts. The HDS series multiples the
elasticity of the screw several times, effectively replacing
conventional spring washers, but not suitable for locking washers
and flat washers.
