13CrMo44 Pressure Vessel Steel DIN 17155, 13CrMo44 Steel equipment parts

KATALOR STEEL
13CrMo44 steel due to chromium, molybdenum two chemical elements to join, it has a minimum yield strength of 290 MPa and 440-590Mpa tensile strength and good plasticity. 13CrMo44 steel is widely used in bridge construction, shipbuilding, machinery manufacturing, gas, oil, water, transportation containers and other steel structures.


Katalor's steel processing plants can deliver 13CrMo44 after hot-forging / hot-rolling + annealing / normalizing + tempering / quenching + tempering according to customer's requirements. Grinding, shot blasting, painting, etc. can also be done on 13CrMo44 surface. Roughing or finishing. We can also 13CrMo44 raw materials processed into steel equipment parts.

Katalor as a well-known domestic steel producers and suppliers, our advantage lies in the excellent team, a wealth of steel processing equipment, and quality and cheap steel products. Our monthly exports of more than one million tons of steel, the huge inventory and rich, subject to overseas buyers praise, if you are interested in 13CrMo44 steel, do not hesitate, please contact us immediately.

P460ML2-Pressure vessel steel weldability




P460ML2-Pressure vessel steel under European standard EN 10028-6,is a thermo mechanically rolled and weldable fine grain steels, usual be used for pressure equipments, like building boilers and pressure vessels such as petroleum, chemical industry, power plants.

P460ML2 steel Extra Service: 
Pretreatment (Shot Blasting, Sand Blast and Painting ), Cutting Parts, Sample Service, Third Party inspection, UT Test and Size inspection.

P460ML2 Weldability:
Basic coated elc- trodes are recommended for manual wel- ding. In general, pre-heating prior to wel- ding or torch-cutting is not necessary. At outside temperature below +5 °C, pre- heating to approx. 50 °C should be car- ried out. Subsequent normalised or stress reli- ef annealing with the grades rolled under normalised conditions is required only if called for in the regulations or if operating and manufacturing conditions make a re- duction of the residual welding stresses appear useful. The thermo-mechanically rolled steels are not suitable for normali- zing; stress relief annealing is possible. With stress relief annealing at 530 – 580 °C, the holding time should be 2 minutes per milimetre of plate thickness, not fall short of 30 minutes and not significantly exceed 60 minutes. Excessively high annealing tempera- tres or excessively long annealing times bear the risk of reducing the strength va- lues to below the condition of delivery.
