Annealing, hardening and heat treatment of lead.

Annealing, hardening and heat treatment of lead.

Are you interested in annealing, hardening of lead? Supplier Avlob offers to buy lead at a bargain price. We guarantee timely delivery of products to any specified address. Regular customers can take advantage of discount discounts. The price is the best in this segment.

Hardening

To ensure that pure lead has higher mechanical properties, the metal should be cooled to below -33 ° C. Practical use was obtained by heat treatment of lead alloys, especially those used in the manufacture of shells of high-current cables. The main type of heat treatment for them is considered to be natural aging, as a result of which the hardness of the material increases to 60… 70 MPa. With an increase in the duration of aging, alloys with these additives acquire additional hardness, but this hardening persists 3… 4 weeks.

Hardening

Hardening is carried out for alloys of lead with antimony. The process consists in heating the alloy to a temperature of 55… 60 ° C and subsequent slow cooling. The ultimate hardness of such alloys reaches 100 MPa. Supplier Avlob offers to buy any non-ferrous metal at a bargain price. The price is the best in this segment of rental.

Increase in corrosion resistance of lead alloys

This technology is used in the production of battery plates. In constantly changing temperature-humidity conditions, lead loses its thermodynamic stability. In order to avoid this negative phenomenon, heat treatment is carried out, which consists in the following:

  • The surfaces of the plates are thoroughly washed and dried;
  • After cleaning, the billets are heat treated at temperatures of 150… 2000 C;
  • After 1… 1.5 hours, the temperature is lowered to room temperature.

As a result of this heat treatment, the corrosion resistance of the surface of the battery plates increases by 30… 40%.
