The strength indexes of pipeline steel mainly include tensile strength and yield strength. At the same time, the yield strength ratio (yield strength to tensile strength ratio) of pipeline steel is also required, which is generally in the range of 0.85-0.93. Pipeline steel shall have enough high impact toughness (crack initiation and crack arrest toughness). For the base metal, when the toughness of the material meets the requirements of crack arrest, its toughness generally can also meet the requirements of crack prevention.
There are a lot of ASTM standards for pressure vessel steel plates. Such as ASTM A204, A285, A302, A387, A515, A516, A517, A537, A612, A841, etc. Those ASTM steel plates have different thickness ranges. , ASTM A204 plates shall not thicker than 150mm. ASTM A285 plates shall not thicker than 50mm. ASTM A515 plates shall not thicker than 200mm. ASTM A517 plates and A537 plates shall not thicker than 150mm. ASTM A612 plates shall not thicker than 25mm. ASTM A841 plates shall not thicker than 100mm.

The Indian iron and Steel Association (ISA) lowered its steel demand forecast for 2020 to 5.1% from 5.1% in February this year. The figure is expected to hit a low of 7.7%. The company said in an official statement that the current share price has fallen sharply due to the huge downside risk. "We expect India's finished steel demand to fall to about 93.7 million tons by 2020, down from 101.5 million tons in 2019." This calendar year, the EN10083-3 51CrV4 heat analysis decline was 7.7%, about 8 million tons. " Isa said.
