There are more than 60 specifications of stainless steel flat-top chain, and its selection should be determined according to the working conditions of the conveyor. The factors involved should include, but not limited to, such as the characteristics of the goods, the requirements of the goods to the environment, the loading capacity, the speed of the chain, the friction coefficient between the chain and the guide rail, the center distance between the driver and driven wheels, lubrication conditions, temperature, etc. Under good lubrication conditions, the transmission line speed of flat top chain can reach 120 m/min.
The technical performance of stainless steel flat top chain mainly depends on its raw materials and technological level of manufacturing process. Different metal materials' characteristics determine the applicable environment and working conditions of flat-top chain products. At present, there are four kinds of chain chain materials for choices: AISI 420, AISI 430, AISI 304 and Special Chromium-nickel Steel. Pin materials are AISI 420, AISI 431 and AISI 304. Among them, AISI 420 chain chain with AISI 420 pin, AISI 430 and Special Chromium-nickel Steel with AISI 431 pin, AISI 304 chain chain with AISI 431 or AISI 304 pinare five assembly methods based on material matching.

Chain Strength
Based on the reliable operation of the open-loop structure chain chain with flat-top chain and the failure elongation not greater than 3% of the nominal length of the chain, its strength should be defined as the actual yield strength of the chain.
Taking 38.1*82.6 single-hinged flat-top chains as an example, the yield strength (green zone) of chains with different materials is shown in the following chart.
The following chart shows the test data of 38.1*82.6 single-hinged flat-top chains produced in March 2017 on 300 Tons universal material testing machine.
Wear
Resistance of Chains
The
wear resistance of the chain mainly depends on the surface hardness and
roughness of the chain chain.
The
surface hardness range (green zone) of chain incha with different materials is
shown in the following chart.
Surface
roughness of chains
The surface smoothness of the chain chain
is usually determined by the Ra value of the arithmetic mean deviation of the
contour.
Stability
of Chain Performance
For the chain itself, the shape and
smoothness of the surface of the chain chain, the side bending and twisting of
the chain, and the gap between the chain chain and the pin shaft are related to
many factors.
The shape of the chain chain is suitable for the transverse movement of objects between multiple chains.
Corrosion
Resistance of Chains
The
test of JW-60-SS salt spray test machine is consistent with the neutral salt
spray test conditions of GB/T 10125 "artificial atmosphere corrosion test
salt spray test" standard. The continuous atomization time of the pitting
phenomenon for the first time of chain incha of different materials is as
follows: Chart: NSS
