Various Steel Bar Delivery Condition
Various Steel Bar Delivery Condition During steel bar purchasing, you may meet some letters which represent abbreviations of various delivery condition. We introduce some of them for you here:
What is cold drawn steel bar? Cold drawn steel bar is produced by hot rolled steel bar or steel wire rod through various moulds with different shapes and dimensions. It is kind of cold finished steel bar. Different from other cold finished steel bar such as peeled or turned steel bar, cold drawn steel bar can n
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.
Cold Drawn Steel Bar Process Cold drawn steel bar has different production and processing flow based on different steel material. There are mainly two kinds processing: Carbon and low alloy steel round bar: Hot rolled steel ro
Cold drawn steel bar tolerances
Cold Drawn Steel Bar Tolerances Cold drawn steel bar has more precision diameter tolerances. The tolerance is as blow. If you want more precision diameter tolerances, we can do grinding on steel bar which can reach 0.02mm tolerance, Ra 0.8um max surface roughness and 0.2mm/m str
Why is steel bar cold drawn? We know steel bar has many kinds of condition such as hot rolled steel bar, cold drawn steel bar, forged steel bar and heat treated steel bar. Do you know why is steel bar cold drawn? Steel bar is cold drawn because the end user need more precision diameter, higher tensile strength and
why is cold drawn steel stronger?
why is cold drawn steel stronger? Do you feel cold drawn steel bar stronger than hot rolled steel bar or peeled, turned bright steel bar? cold drawn steel bar is stronger because the tensile strength, yield strength and hardness are higher than hot rolled steel bar. Steel bar through cold drawing can not only change the diameters, surface, but also change the mechanical properties. Because
High strength prestressed anchor
High-strength prestressed anchor bolts are used in places with harsh environments. They have to pass the test of severe winter and heat. On the premise that the mechanical properties of the product meet the requirements, they must also meet the requirements of low-temperature impact toughness and surface treatment salt spray test. Mechanical performance requirements of wind power bolts Among them, quenching and tempering heat treatment is the key to the process; the company is committed to high-performance heat treatment of various steels to ensure the accuracy and consistency of product perfo

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
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
