BDF is able to produce a wide range of sizes bolts by cold or hot forging. The diameter of bolts ranges from M6-M80 in Metric and 5/16” to 3 1/2” in Inch, and length can be up to 1000mm for bolts.

W.Nr.1.4547 is different from ordinary stainless steel in chemical composition. It refers to a high-alloy stainless steel containing high nickel, high chromium, and high molybdenum. The most famous of these is 254SMo with 6% Mo. This type of steel has very good resistance to localized corrosion. It has good resistance to pitting corrosion (PI 40) under seawater, aeration, gaps, and low-velocity erosion conditions.  

Good stress corrosion resistance is an alternative to Ni-based alloys and titanium alloys. Second, in the high-temperature or corrosion-resistant performance, with better high temperature or corrosion resistance, 304 stainless steel can not be replaced. In addition, from the classification of stainless steel, the special stainless steel metallographic structure is a stable austenite metallographic structure.
