MMFX Steel Corporation of America, Irvine., Calif., and Williams Form Engineering Corp., Belmont, Mich., are partnering to expand the Williams Form line of high-strength and corrosion-resistant products for the construction industry. MMFX Steel achieves its unique steel properties through a combination of the alloying elements and a well-controlled manufacturing process. The resulting low-carbon chromium alloy steel has a microstructure that is strong yet ductile and inherently corrosion-resistant.
Williams Form will use MMFX2 and ChromX 4100 steels from MMFX to manufacture its new uncoated corrosion-resistant and high-strength threaded bar products. The line will complement Williams Form’s existing threaded bar products for applications such as soil nails, tieback and rock anchors, micropiles, and wind turbine foundation bolts.
Under the new agreement, Williams Form will develop thread bar products using the innovative MMFX steel technology. The new product line will provide engineers with new design solutions for geotechnical, post tensioning and concrete accessory applications that can benefit from corrosion-resistance and high-strength properties.
The existing Williams Form threaded bar options for corrosion resistance include epoxy-coated, galvanized and grouted carbon steels. The uncoated steels from MMFX alleviate user concerns about damaging epoxy coatings or fastener thread fit-up issues that can result from galvanizing. The high-strength properties of the MMFX steel will also allow Williams Form to manufacture products that meet its wide range of tensile strength requirements.
By using the MMFX material properties, the Williams Form all-thread bar product line will conform to the high-strength properties of ASTM A1035. The finished products will have a tensile strength up to 150 ksi and feature the Williams Form proprietary thread.
