[MW:27240] RE: 27229] Material Selection for Conveyor chain

By Materials & Welding

Sodium Silicate is not much corrosive , either as flakes or when molten. In fact various literatures suggested use of this chemical as corrosion inhibitors under different conditions.

 

The crucial factor could be continues heating and water quenching cycle , which could introduce thermal fatigue.

 

One simple solution, with respect to change material of construction could to switch to 310 SS (https://www.rolledalloys.ca/alloys/stainless-steels/310/en/). This may help.

 

Thanks.

Subject: [MW:27229] Material Selection for Conveyor chain

 

Dear Experts.

Could anyone suggest the right material for a conveyor chain; following is the service condition:

Temperature: 450 deg C in one run and quenched by water in the return run,

Cargo: Sodium Silicate Flakes received in molten phase and conveyed in open air

Material currently being used: SS304 the life of the chain is 6months maximum.

Thank you very much

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
