What harm does the excessive weld height of a242 type 1 corrosion resistant steel quality bring

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and a242 type 1 corrosion resistant steel quality heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported a242 type 1 corrosion resistant steel quality to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Shipbuilding steel plates or offshore platform plates are used to make hulls, offshore oil production drilling, platform pipe joints and other structural parts; Our ship steel plates are nine classification societies certified( American ABS, French BV, British LR, German GL, Norwegian DNV, Italian RINA, Japanese NK, Chinese CCS, South Korea KR ). a242 type 1 corrosion resistant steel quality, These plates can be Z15 / Z25 / Z35. Our company stocks a large number of shipbuilding plates, a242 type 1 corrosion resistant steel quality, offshore platform plate steel in stock.

a242 type 1 corrosion resistant steel quality, Wear-resistant steel plate has good heat resistance:
The alloy wear-resistant layer is recommended to be used under ≤600℃. If vanadium, molybdenum and other alloys are added to the alloy wear-resistant layer, it can withstand high temperature wear of ≤800℃. The recommended operating temperature is as follows: Ordinary carbon steel base plate is recommended to be used in working conditions not higher than 380℃; Low-alloy heat-resistant steel plates (15CrMo, 12Cr1MOV, etc.) substrates are recommended to be used in working conditions not higher than 540℃; The heat-resistant stainless steel substrate is recommended to be used at no higher than 800℃.

With the increase of temperature, the yield limit of a242 type 1 corrosion resistant steel quality will decrease monotonically, but the tensile strength of a242 type 1 corrosion resistant steel quality will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of a242 type 1 corrosion resistant steel quality. Near the blue brittleness temperature, the a242 type 1 corrosion resistant steel quality strength increases and the plasticity decreases. The elongation and section shrinkage of a242 type 1 corrosion resistant steel quality increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

The carbon content of a242 type 1 corrosion resistant steel quality, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
