The full name of 304 stainless steel pipe is SUS304 stainless steel pipe. SUS304 stainless steel pipe belongs to the stainless steel pipe made of American trademark. It is equivalent to Chinese grade 0Cr19Ni9 stainless steel pipe, which is generally replaced by 0Cr18Ni9. The mechanism of stainless steel rust prevention is that the alloy elements form a fine oxide film, which insulates the touch of oxygen and prevents continued oxidation.
After quenching and tempering, 40Cr alloy steel plate and RINA EH40 hull structural ship plate sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel RINA EH40 hull structural ship plate is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.
The correct choice of billet type, section shape, size and weight are of great significance to RINA EH40 hull structural ship plate steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The RINA EH40 hull structural ship plate rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.
There is a silo technology R&D center in our company with many experts. Our technical backbones go abroad to study advanced technologies regularly to make our technology and products leading in the world. We provide our customers with RINA EH40 hull structural ship plate high-quality steel plates, the excellent quality from specialty. With good reputation, high-quality products, strong strength, and low prices, we welcome the clients from the world to come to visit our factory.
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the RINA EH40 hull structural ship plate principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
