Choosing between black iron and stainless steel is NOT all there is to material selection!
There's a bunch to pick from... iron-based copper, aluminum, nickel, cobalt titanium, zirconium, rare earths corrosion resistant alloy (CRA) super alloys ceramics, refractories polymers/plastics composites wood					Lots of fabrication concerns purchase specifications basic design stress analysis thermal treatment joining procedures welding procedures welder qualification repair procedures protective coatings					Quality Control issues mechanical testing nondestructive inspection positive material identification (PMI) field metallography
										OK, you got the test results, but... A second opinion might improve confidence The facts are presented in a confusing format Maybe the wrong test was performed
After twenty years in a commercial materials testing laboratory Dr. Claude Mount, PE understands the many aspects of using engineered materials.
