Abstract
An item made of wear resistant material, the item, in certain aspects, made by a method including forming a mass of wear resistant material, the wear resistant material comprising at least one element from the group consisting of arsenic, antimony, cerium and bismuth, wherein the at least one element is present by weight as between 0.01% to 0.0001% of a total weight of the wear resistant material, wherein the wear resistant material includes by weight percent chromium 29.10-30.00%; nickel 5.00-6.00%; titanium 1.00-2.10%; boron 3.00-3.90%; silicon 1.00-2.10%; manganese 1.10-2.00%; iron-balance.

An item made of wear resistant material, the item comprising
- a body of wear resistant material,
- the wear resistant material comprising at least one element from the group consisting of arsenic and bismuth,
- wherein the at least one element is present by weight as between 0.01% to 0.0001% of a total weight of the wear resistant material,
- wherein the wear resistant material includes by weight percent chromium 29.10-30.00%;
- nickel 5.00-6.00%;
- titanium 1.00-2.10%;
- boron 3.00-3.90%;
- silicon 1.00-2.10%;
- manganese 1.10-2.00%;
- iron—balance.
An item made of wear resistant material, the item made by a method comprising
- forming a molten mass of wear resistant material, the wear resistant material comprising at least one element from the group consisting of arsenic, antimony, cerium and bismuth,
- wherein the at least one element is present by weight as between 0.01% to 0.0001% of a total weight of the wear resistant material,
- wherein the wear resistant material includes by weight percent chromium 29.10-30.00%;
- nickel 5.00-6.00%;
- titanium 1.00-2.10%;
- boron 3.00-3.90%;

- manganese 1.10-2.00%;
- iron—balance,
- wherein the wear resistant material includes a plurality of spaced-apart pieces in the shape of acicular needle-like pieces, the spaced-apart pieces uniformly dispersed in the wear resistant material and interlocked with each other for resisting cracking of the wear resistant material,
- wherein the item is formed by using a molten amount of the wear resistant material,
- wherein the item is an ingot, and
- wherein the acicular needle-like pieces have a first dimension and a second dimension, the first dimension at least 70% larger than the second dimension.
A method for making an item, the method comprising
- forming a mass of wear resistant material wherein the wear resistant material includes at least one element from the group consisting of arsenic and bismuth,

- wherein the wear resistant material as applied is present as a plurality of spaced-apart pieces in the shape of acicular needle-like pieces, the spaced-apart pieces uniformly dispersed in the wear resistant material and interlocked with each other for resisting cracking of the wear resistant material, and
- wherein the wear resistant material includes by weight percent chromium 29.10-30.00%;
- nickel 5.00-6.00%;
- titanium 1.00-2.10%;
- boron 3.00-3.90%;
- silicon 1.00-2.10%;
