Embodiment Construction

[0019] The following description of the embodiment(s) is merely exemplary (demonstrative) in nature and is in no way intended to limit the invention, its application or uses.

[0020] see now figure 1 , an exemplary embodiment includes an article 10 having a low chromium content steel core 12 coated along at least one surface 13 with a carbide coating 14 .

[0021] For purposes herein, a low chromium steel core 12 contains less than about 1.6% chromium. The term "steel core" is used herein interchangeably with the term "steel substrate" and refers only to the low chromium content steel surface where the article includes a carbide coating 14 to be applied. All percentages herein are by weight.

[0022] An exemplary embodiment of a low chromium content steel that may be used in steel core 12 is AlS152100 (UNS-G-52986) steel, which has the following nominal composition: 0.98-1.1 weight percent carbon; 0.25 - 0.45 weight percent manganese; 1.3-1.6 weight percent chromium; 0.025...
