Inquiry (采购产品): 5.56mm grade 70 steel I'm looking for 5.56MM or 7/32"(.218) AISI 1018 CW grade 70 steel for a newly patented roof bolt plate. These plates are for use in underground mines and I need samples to do an ASTM test for MSHA. I would also like to test .1875 70 grade. I could use at least ten, eight inch square plates of each thickness. If these pass it could mean making hundreds of thousands of these plates. **** Hidden Message ***** Bert Slater Indiana, PA 15701 USA Company: Slater's Phone: 724- 525 1295 E-mail: slater11@msn.com **** Hidden Message ***** slater11@msn.com
