Precipitation-Hardening Stainless Steel Fasteners and Material Options
Precipitation-hardening stainless steel material options can be discussed for industrial fasteners, stud bolts, threaded rods, bolts, nuts, washers, anchors, special fasteners and drawing-based custom parts where 17-4PH or other project-specified PH stainless steel grades and material conditions are specified by project requirements.
PH Stainless Steel Materials for Project-Specified Fasteners
Precipitation-hardening stainless steels are stainless-family materials commonly discussed for project-specified industrial fasteners and custom parts where procurement documents specify 17-4PH, PH grade, UNS / EN / ASTM / AMS designation, material condition, heat treatment note or drawing requirement.
WISINE can discuss PH stainless steel stud bolts, threaded rods, bolts, nuts, washers, anchors, special fasteners and drawing-based components according to confirmed material grade, product form, material condition, quantity, processing requirements and document requirements. 17-4PH and other PH stainless grades should not be treated as interchangeable without project confirmation.
