	Plasma cutting stainless steel and aluminum: Investigating thermal and chemical changes in the heat-affected zone By: Charles M. Hackett, Contributing Writer This study conducted at Hypertherm characterizes thermal and chemical changes in plasma-cut stainless steel and aluminum alloys and recommends process alternatives that may improve aesthetics and cut quality to improve forming and fabricating of the materials. The systems used were water-injection PAC, conventional dual-gas PAC, and high-precision PAC. It was learned that the heat-affected zone (HAZ) is small in plasma-cut pieces, HAZ varies with speed and power, faster cutting produces less HAZ, and more heat per square inch can produce less HAZ.

	A 'weld-done' finish: Proper equipment and techniques that meet the challenge of finishing stainless steel welds By: Tom Carroll Stainless steel products are used in all parts of our daily life. Certain surface finish expectations must be met, and one of the major challenges in stainless steel treatment is meeting these expectations. The biggest problem has been the time required to rebuild the surface from a weld. While surface finishing of stainless steel still requires a good deal of effort, the proper grinding and polishing equipment makes it possible to create perfect finishes in a reasonable amount of time.
