Medium Tensile Carbon Steel Bar 1045 Atlas 1045 - Atlas Steels

Atlas Specialty MetalsMedium Tensile Carbon Steel Bar 1045Applications of Atlas 1045Grade 1045 is used in general engineering applications. This grade is used inengineering applications where better strength that that offered by either M1020 orM1030 is a requirement. Typical applications include hydraulic rams, shafts andmedium to higher strength threaded fasteners. Atlas 1045 is generally notrecommended for critical applications, particularly those where high strength isrequired in combination with ductility or toughness. For these application low-alloysteels are generally recommended (or in certain cases micro-alloy steels).Possible Alternative GradesGrade Why it might be chosen instead of 1045Where a lower tensile and yield strength grade is acceptable. If gradeM1030 M1030 is used as an alternative then pre and post heat would normallystill need to be used, particularly in heavier sections.Further increase in strength required, plus guaranteed tensile propertiesare a requirement. Better impact properties are required. Higher core4140 strength required. Welding of grade 4140 would not normally berecommended. In case of attempting to weld this grade guidance froman experienced and qualified welding engineer must be sought.DisclaimerWhilst every effort has been made to ensure accuracy of the information in this Datasheet, Atlas SpecialtyMetals accepts no liability for damages arising from its use.Revised April 2006 4 of 4
