On carbon steel (black)

Designation: Sn

Synonyms: Tinning.

Price: from 10 rub. per dm²

Purpose: Tin coating on steel is used for < undefined:p>improving solderability and electrical conductivity,protection  steel electrical contacts from oxidation, creating an easily break-in layer on rubbing surfaces, as well as protection against corrosion in some environments.</undefined:p

Adding bismuth to the coating allows you to: maintain solderability for up to 1 year, slow down the transition of the ductile white modification of tin to gray powder, slow down needle formation. 

Designation: Sn

Synonyms: Tinning.

Price: from 10 rub. per dm²

Purpose:Tin-lead coating used for: improving solderability (tin-lead(60)) andcreating an easily run-in layer on the rubbing surfaces (tin-lead (10)).Adding lead to the coating allows:maintain solderability for up to 1 year,slow down the transition of the plastic white modification of tin to powder gray, slow down the needling. Other percentage coating compositions are possible. Can replace Horizontal POS coverage
