Hot-rolled wire rod for prestressed steel wire and steel strand (YB/T146-1998)
.
Pre-stressed Steel Wire and Steel Strand by Hot Rolled Coil (YB/T146-1998)
Pre-stressed steel wire and the steel strand are usually manufactured by a hot rolled coil process to produce good toughness and a durable, uniform surface finish. The hot rolled steel coiling process involves heating the......
Steel bars for prestressed concrete (YB/T111-1997)
Abstract
This article introduces the technology of steel bars in pre-stressed concrete. It consists in three parts. The first part introduces the characteristics of steel bars in pre-stressed concrete, namely, the tensile strength, elastic modulus and so on. The second part gives the structure of......
Hollow steel for rock drilling rods (GB/T1301—1994)
Hollow steel, also known as hollow steel, is a kind of steel cross section made of uniform thickness rolled and welded steel, which is also called divided steel. It is an iron and steel material with different shapes and wall thicknesses. It is mostly used for steel columns, steel beams, steel sca......
Ultrasonic flaw detection and quality rating method for steel castings (abstract) GB 7233-87
Abstract
This study focused on the ultrasonic nondestructive testing and quality evaluation method of cast-steel parts. The study reviewed and evaluated the current testing capabilities of various establishments, including the simulation tests and judgment criteria of surface and internal defects......
Classification method of radiography and film grades of steel castings (abstract) GB 5677-85
X-ray photography and film grading of castings is a widely accepted practice used to detect any discontinuities and flaws in the casting. In recent times, this method has become a standard to evaluate the quality of castings and to determine the necessary measures needed to achieve certain quality......
Cast steel roll (GB/T1503-1991)

GB 13013-91 Hot-rolled straight and smooth round bars for reinforced concrete
，
Hot rolled straight round steel bars for reinforced concrete in GB 13013-1991 has been the most commonly used non-alloy and low alloy steel bars in China, used for the construction and reinforcement of concrete structures.
The steel bars used in GB 13013-1991 have good plasticity and toughness,......
1Cr17Mn6Ni5N use
AISI 430 (1Cr17Mn6Ni5N) stainless steel is a type of ferritic stainless steel developed for maximum corrosion and heat resistance. Like other ferritic alloys, AISI 430 has a high chromium content but is also balanced with low levels of carbon, so it does not become brittle at elevated temperatures......
