Steel grades are often defined using a standardized system developed by organizations such as the American Society for Testing and Materials (ASTM), the Society of Automotive Engineers (SAE), and the International Organization for Standardization (ISO). These grading systems include designations like A36, A572, or 1020, representing differences in carbon content, tensile strength, and other properties.
S235JR, S235J0 and S235j2 steel is a structural steel grade which be used in riveted, bolted, or welded construction of bridges and buildings.235 indication of the min specified yield strength for thickness of under 16mm. JR symbol 20 temperature impact test. J0 symbol 0 temperature impact test. J2 symbol -20 temperature impact test.
1045 is a medium carbon steel is used when greater strength and hardness is desired than in the "as rolled" condition. Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. Commonly used in gears, shafts, axles, bolts, studs and machine parts.
AISI 1018 carbon steel is a free machining grade that is the most commonly available grade around the world. Although its mechanical properties are not very unique, it still can be easily formed, machined, welded and fabricated.
ASTM A516 Pressure Vessel Steel Plate/Boiler Steel Plate
ASTM A516 covers pressure vessel steels with excellent notch toughness levels. Distinct grades are offered with different tensile strengths and thicknesses to suit individual customer requirements.
ASTM 1020 steel stands as a cornerstone material, widely utilized across industries ranging from automotive and manufacturing to construction and agriculture. Its popularity stems from a unique combination of properties that make it a versatile and cost-effective choice for numerous applications.
NM500 is a high-strength wear-resistant steel plate with high wear resistance. Its Brinell hardness value of 500 (HBW) is mainly used to provide protection in situations or parts that require wear resistance, prolong equipment life, reduce maintenance and downtime, and correspondingly reduce capital investment.
AH36 steel plate is a steel plate with a thickness of no more than 150 mm for the manufacture of ocean going, coastal and inland navigation ships, fishing boats and offshore engineering structures. For steel plates with Z-direction requirements, add Z25 and Z35 to the suffix, which is used as structural steel for high-strength ships and offshore engineering.
Structural unalloyed steel S355JR has a wide range of applications in construction, metallurgy, heavy and transport engineering, machine tool, power engineering and bridge building industries. Various profiles and metal structures, parts and elements of ground and underground equipment are made from steel S355JR.
