We then metallographically examine and characterize the test bars. The various standardizing committees review the data in our reports, decide on mandatory and typical properties and then issue their standard specifications. Heat treated tensile and rotating beam fatigue bars are machined from the unnotched Charpy bar, which is 10x10x75 mm. As a control measure, our green bars are often sintered by parts producer's, allowing them to show process control. 960X Photomicrograph, etched structure of a sintered air-hardening low alloy steel.
Shows mainly tan martensite with some pearlite.
Dark areas are pores. We have the ISO standards for metal powders and parts, and carry out those test methods. Powder-Tech Associates answers this need by being organized to make prototype discs in quantities from one piece to a few hundred pieces, and to ship them in two to four work days. James Collette and David Pease operate our pilot plant and produce the prototype materials. To provide this quick response, they do everything from preparing quotations, to taking orders, mixing, pressing, sintering and shipping.
