ST52/45#/Q345/16Mn seamless steel kav

Tsis Npawb Tswv Txiaj:

Cov xwm tawm qhov ntawv yog mus rau li cov qab ntsuam steel hoob. Cov steel ntawv qhov ntawv thiab txog qab ntsuam ua siab los ntawm qab ntsuam, thiab yog ib qhia ua hauv qhov ntawv steel ntawv. Nrog qhov npawb ntawd, cov ntawv steel ntawv tej kev muaj hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, thiab jacked pipes. Nrog qhov qab ntsuam, cov ntawv steel ntawv tej kev muaj ib qho yim thiab ib qho yug yug. Cov yug yug ntawv muaj qhov yug yug lwm thiab qhov yug yug special-shaped. Special-shaped ntawv muaj qhov yug yug lub yug yug, oval, triangle, hexagon, melon-shaped, star-shaped, thiab finned ntawv. Lub qhov qab sib xaiv yog 900mm thiab lub qhov qab sib noj yog 4mm. Nrog qhov yooj hais, muaj cov thick-walled seamless steel pipes thiab thin-walled seamless steel pipes. Cov ntawv steel ntawv tej kev muaj ua hauv qhov tub rig kub thiab geology drilling ntawv, cracking ntawv rau li petrochemical industry, boiler ntawv, bearing ntawv, thiab high-precision structural steel ntawv rau li cov tshoob thiab tractors thiab aviation.

Q345 steel pipe, yog peb 16Mn, 16Mn ntawv txheej steel pipe li cas tsev low alloy steel. Yog li cas tsev los yuav tsum nrog boilers thiab pressure vessels. Yog li hot rolled los normalized. Yog li low alloy steel ntawm low Mn content. Ntawm lub performance li yog cov xovxwm 20G (412-540), tensile strength li noj yog cais (450-655), thiab elongation li 19-21%, yog kawg tau 20G li yog noj 24%.

16Mn ntawv txheej steel pipe li cas tsev special plate nrog pressure vessels ntawm yield strength 340MPa. Yog li cas tsev los yuav tsum kom paub mechanical properties thiab process performance. Phosphorus thiab sulfur content li noj yog caij los ordinary 16Mn steel. Yog li cas tsev los yuav tsum kom paub tensile strength thiab elongation requirements noj yog caij ordinary 16Mn steel, thiab impact toughness li yuav tsum kom paub ensured. Yog li cas tsev special steel plate los yuav tsum kom paub thiab widely used nrog pressure windows nyob rau hais lwm teb.

tsawg 45# : cov txhais ntawv ceeb yuav rau 0.42-0.50%, cov txhais silicon yuav rau 0.17-0.37%, cov txhais manganese yuav rau 0.50-0.80%, cov txhais sulfur <=0.035%, cov txhais phosphorus <=0.035%, cov txhais chromium <=0.25%, cov txhais nickel <=0.2545 tsawg

Piav qhia:

Cov txog ntawm ua siam los noj cov kev caij teb chaw, los yim mus rau daim ntawv, ua rau hno qab ntsiav thiab ua rau hno thiab nyob rau hno.

Specifications:

Tawb ceeb qhov tsev teeb peb

Daim Ntawv Thov:

Thiaj rau hwm lub kev txong, yuav tshaj los ntawm taufov, nyob rooj, dab qhov no, xoom, kheej chaw, thiab muaj kev cov nrog.

Tsis Ntawm Ntsuam:

Cov fab yog mus ua hauv qhov tshaj los npawb qhov, ua hauv qhov tshaj los npawb thiab tech, tsis paub tuaj yim ua hauv tub qeeb tshaj los muaj hauv hais tsev thiab model. Qhov tej ntawv yog ua hauv, qhov raug raug yog hais txog, thiab lwm 7*24 lub ntsuam ntawm lawv raug raug.
