Alloy for backing steel of a bimetallic band saw blade
First Claim
1. An improved bimetallic band saw blade having a high speed steel cutting edge and a backing steel band welded thereto, saw teeth formed along the high speed cutting edge including cutting tips and gullets, said cutting tips being formed in the high speed steel edge and-the gullets extending into the backing band, said backing band comprising, by weight from 0.5% to no more than 1.50% Chromium (Cr), 0.10% to 0.75% Vanadium (V), 1.5% to 2.50% Molybdenum (Mo) and wherein said backing band comprises a substantially lesser amount by weight of Chromium than Molybdenum, the backing band alloy also containing Carbon (C), Manganese (Mn) and Nickel (Ni) in such varying amounts that the total alloy content of the backing band, except for iron and inevitable impurities, is in a range of 3.12% to 8.84% by weight.

Abstract
A bimetallic band saw blade has a high speed cutting edge welded to a backing band of a steel alloy containing the following elements percentages by weight:
Cr - 0.5% to no more than 1.5%
V - 0.10% to 0.75%
Mo - 1.5% to 2.5%
wherein said backing band comprises a substantially lesser amount by weight of Chromium than Molybdenum the alloy also contains C, Si, Mn, Nb and/or Ni and Al in such varying amounts that the total alloy content, except for Fe and inevitable impurities, is in the range of 3.12% to 8.48%.
