Reduce S355ML material specification price

Large-thickness S355ML material specification, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than S355ML material specification. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel S355ML material specification is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

The Iranian government recently imposed new restrictions on steel exports, requiring exporters to obtain an export license issued by the Ministry of Industry, Mine and Trade before exporting. According to the latest restrictions, all Iranian steel producers must give priority to meeting domestic demand on the Iranian commodity exchange (IME) platform before being allowed to export. The new restrictions are aimed at reducing the country's S355ML material specification and so on steel exports.
