Effect of humidity and temperature on corrosion of TMCP CCS EH32 engineering ships steel

Precautions for procurement of TMCP CCS EH32 engineering ships steel, corrosion resistant steel. First, thickness. According to the thickness, corrosion-resistant steel can be divided into thin plate, medium plate, thick plate and extra thick plate, and each thickness has different application fields. Second, the choice of length and width, which can be cut to required size. Third, standards, each country has its own standards, so when purchasing corrosion resistant steel, it depends on which country it is used. Fourth, it is better to let professionals to purchase TMCP CCS EH32 engineering ships steel or corrosion resistant steel.

Based on the main TMCP CCS EH32 engineering ships steel business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and 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 TMCP CCS EH32 engineering ships steel products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Titanium microalloying is an element of TMCP CCS EH32 engineering ships steel strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in TMCP CCS EH32 engineering ships steel tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of TMCP CCS EH32 engineering ships steel etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in TMCP CCS EH32 engineering ships steel etc. steel is strictly controlled.

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
