Khalandrion201 stainless steel pipeAccuracy analysis

Continuous casting shall be adopted for stainless steel pipe fittings, so as to improve the comprehensive yield, and cooperate with out of furnace refining, which significantly improves the production efficiency, omits the blank opening process and saves a lot of energy consumption.AUSTENITIC FERRITIC duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel, and has superplasticity. Martensitic stainless steel. High strength, but poor plasticity and weldability.Khalandrion,Mechanical properties when the steel or sample is stretched, when the stress exceeds the limit, even if the stress is no longer increased, the steel or sample continues to have obvious plastic deformation, which is called yield, and the small stress value when the yield phenomenon occurs is the yield point.CE--“ Code for design of cold formed stainless steel structural parts & rdquo; And & ldquo; jointly published by nidi and euro inox; Structural stainless steel design manual & rdquo; The design of structural parts for buildings with long service life and good integrity has been simplified.Monte Patria, Series & mdash; Martensitic precipitation hardening stainless steel.Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.Stainless steel pipe is a kind of economical section steel and an important product in the iron and steel industry. It can be widely used in life decoration and industry. Many people on the market are used to make stair handrails,KhalandrionStainless steel wire drawing tube, window guards, railings furniture, etc. and materials are common.

The product quality advantages of continuous casting billet of stainless steel pipe fittings are mainly reflected in that the non grinding rate of the outer surface of the billet except the head and tail section has reached more than %, and the total surface grinding yield has reached %. In order to achieve this goal, achieve low oxygen and sulfur content do a good job in the metallurgy of the ladle and tundish, accurately determine the molten steel temperature, and realize no oxidation casting, Further reduce the inclusion content.The welding performance is also much better than that of ferritic stainless steel. Generally, preheating is not required before welding and heat treatment is not required after welding.After fine tuning the molten steel temperature in the argon blowing station, it is lifted to the ladle rotary table for continuous casting.index, Series & mdash; Martensitic precipitation hardening stainless steel.The slab solidified on the surface continues to be rapidly cooled through the secondary cooling section until the core becomes solid, and the whole continuous casting process of stainless steel pipe fittings is completed.At low temperature, ferritic stainless steel pipe has low-temperature brittleness like carbon steel, but austenitic steel does not. Therefore, ferritic or martensitic stainless steel produces low-temperature brittleness, high purification process can be considered. With the help of C and N level it is necessary to pay special attention when using at low temperature. As a way to improve the impact toughness of ferritic series stainless steel, the embrittlement temperature is in the range of - ℃ to - ℃

Stainless steel export is an important part of China's export economy. It plays an important role in stimulating China's economic growth. However, from the current situation of China's stainless steel foreign trade, China's stainless steel export has encountered great resistance.The cost is reasonable,At present, thin strip, roll strip,Khalandrion304 stainless steel pipe standard, calendering strip and other strips can be cut with a thickness of . to mm (Note: stainless steel calendering strips of various thickness and width can be produced according to the needs of customers)Marking: in order to make the steel pipe complete the socket of the pipe fitting, the length must be marked and marked at the pipe end.Khalandrion,;- Ferromagnetism due to m transformation shall be considered in use (such as in instrument parts).Production process of stainless steel welded pipe: raw material - strip - welded pipe - end repair - polishing - Inspection (spray printing) - Packaging - shipment (warehousing) (decorative welded pipe).Stress corrosion cracking (SCC) refers to the cracking caused by the combined action of stress corrosion stress (mainly tensile stress) and corrosion of austenitic stainless steel Austenitic stainless steel is prone to stress corrosion in corrosive media containing chloride ions. When the Ni content reaches % - %, it is a long-term enterprise engaged in stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe. Welcome to consult. The stress corrosion tendency of austenitic stainless steel is very large. Continue to increase the Ni content to ~ %, and the stress corrosion tendency gradually decreases until it disappears.
