ABSTRACT:
An improved passenger car tire chain employing heat treated medium carbon steel is disclosed. The improved tire chain is approximately twice as durable as that presently furnished to meet NACM-5179(TC) for Type PL chains when AISI 1026 or 1029 carbon steel is employed at least for links of a cross chain meeting the road surface. The cross chain links are closed by welding prepared abutting link ends which have been previously beveled. After being welded closed, the cross chain links are case hardened, quenched, tempered and air cooled. The improved tire chain is then assembled in a conventional manner to include a pair of side members, fastening means to secure a end of each side member to the other end, and a plurality of cross chains extending between the sidewall members at preselected intervals.
