Unifit Metalloys Inc. is one of the known suppliers of Stainless Steel ASTM A194 Grade 6 / 6X Fasteners, which is promptly fabricated by a standard commercial process. Finishing temperature of Stainless Steel ASTM A194 Grade 6 Nuts should be done above 950 Degree C. The tacks in Stainless Steel ASTM A194 Grade 6X Bolts should be subsequently grinded or at least be free from crater cracks. Other corrosive compounds such as water and sulfur compounds in Stainless Steel ASTM A194 Grade 6 Washers will significantly reduce the maximum service temperature.
Stainless Steel ASTM A194 Grade 6X Screws offers good oxidation resistance in intermittent service to 840 Degree C and in continuous service to 900 Degree C, although not usually chosen for this environment. In wet environments, the high carbon content in Stainless Steel ASTM A194 Grade 6 Hex Head Nuts works as a limitation.
Stainless Steel ASTM A194 Grade 6X Hex Head Bolts is used in oven linings, boiler baffles, kilns, lead pots, radiant tubes, annealing covers, saggers, burners, and so on. Most common hot work methods for Stainless Steel ASTM A194 Grade 6 Hex Head Screws can be successfully performed after uniform heating to 2150 Degree F (1177 Degree C). Stainless Steel ASTM A194 Grade 6X Flat Washers is non-magnetic in the annealed and cold worked conditions and is as resistant to corrosion as other alloys.
