Wholesale Tube For Drill Rod Grade AISI/SAE 1541 is a medium carbon alloy steel. As an alloying element, manganese, when added to the alloy, enhances properties such as strength, hardness, and hardenability. Manganese also improves the abrasion resistance properties, making it well suited for high stress applications such as mining and drilling. 聽 With cold drawing and stress relieving, 1541 SR tubes have outstanding mechanical properties, high hardness, good wear resistance and longer fatigue life. 聽 Product Details 聽 Product Name ASTM A519 1541 stress relieved drill rod tube StandardASTM A519 Material1541 DimensionOD: 16-245mm, WT1-32mm LengthAccording to client鈥檚 requirements StraightnessStandard Class: 0.5/1000mm; Superior Class: 1/3000mm Delivery ConditionStress Relieved Annealed (SRA) CertificateISO 9001, IATF 16949 ApplicationsDrill rod, casing, core barrel inner tube and outer tube 聽 Drill Rod Dimensions 聽 Spec.OD (mm)ID (mm) AQ44.4535.05 BQ55.5546.05 NQ69.8560.45 HQ88.977.8 PQ114.3101.6 聽 Chemical Composition 聽 Steel GradeCMnPS 15410.36-0.441.35-1.65鈮?.040鈮?.050 聽 Mechanical Properties 聽 Steel GradeDelivery ConditionTensile Strength Min (Mpa)Yield Strength Min (Mpa)Elongation MinHardness (HRC) 1541+SR82073015%鈮?4 聽 Advantages 聽鈼?High wear resistance and longer fatigue life 鈼?High straightness with special attention to tube ends 鈼?Low residual hoop stresses 鈼?Tight dimensional tolerances, low eccentricity 聽 Quality Control 聽 We understand the importance of straightness, mechanical properties, and tolerance accuracy to mining and drill industry.
