AVIATIONEU NEW ERA 4130/4140 Alloy Steel Round Bars/Rods (CTO)SKU: AVEUNE-RNDBAR-ST4130/ST4140-CTO

AISI/SAE(*) 4130 and 4140 grade steels are low-alloy steels containing chromium and molybdenum as common composition elements. Both are are popular steel materials due to their properties. AISI 4130 grade steel shows good overall combinations of strength, toughness and fatigue strength with good atmospheric corrosion resistance while AISI 4140 grade steel features a high fatigue strength, abrasion and impact resistance, toughness, and torsional strength. Both alloys are weldable with the use of all conventional techniques (AISI 4130 alloy's lower carbon composition compared to AISI 4140 allows easier welding) and machinable in the annealed condition. To make them stronger they need to be subjected to heat treatment, such as annealing, cold working, etc. 4140 and 4130 grade steels are wideky used in aerospace, oil and gas, automotive, agricultural and defense industries.

Round bars from AISI 4130/4140 structural steel alloys are offered as part of AVIATIONEU NEW ERA product lines for a wide range of uses in different applications (gears, connection rods, stem assemblies, pump shafts, tool holders and others. Sourced from quality producers, they are competitively priced and offered in different diameters ( 5.5-500 mm), pre-cut (5.8m, 6m, 11.8m) and cut to order lengths, consisting a cost effective solution when large quantities of such sheets are demanded. Unit of sale is 1 Ton (US or Metric as specified) with Minimum Order Quantity (MOQ) 3 Tons. Sea/sea-surface transport to customer destinationcan be provided. Approximate time for shipping: usually 1-2 months from the time of order payment depending on the ordered quantity. Appearing price is indicative per unit of sale.
