what is cold drawn steel material?

what is cold drawn steel material? Cold drawn steel bar raw amterial is usually hot rolled steel bar or steel wire rods. For diameters below 16mm, hot rolled steel wire rod is mostly used because the production effciency and pass percentage is higher, so the price us relatively more competitive. For diameters above 16mm, hot rolled steel round bar is more used because the wire rod is rare if less quantity.

Chrome Molybdenum Steel and High Temperature Applications

Chromium-Molybdenum Alloy Steel (or Chromium-Molybdenum), is an alloy used for high pressure and high temperature applications. It is used in the oil and gas, energy, construction and automotive industries due to its corrosion resistance, high temperature and tensile strength. Chromium-molybdenum steel-often referred to simply as chrome-molybdenum steel-is a low-alloy steel used in many applications and industries. As the name suggests, two key alloying elements are molybdenum (Mo) and chromium (Cr). These alloys are usually grouped into one main category, and the common names are Chrom

ASTM F1554 Threaded Rods

All our threaded rods are manufactured using thread rolling machines. Rolled threads are formed by pressing a thread die into the shank to move the excess metal outward. F1554 anchor bolts are commonly used in civil construction of commercial and industrial projects. Applications include: light and metal poles, commercial buildings, and anchoring structural steel to foundations. Grade 36 anchor bolts have the lowest yield strength compared to other grades in the F1554 specification. ASTM F1554 Grade 36 Anchor Bolts are made of A36 mild steel. This is your standard common b
