1: AISI 1035 Steel introduction
AISI 1035 is a low-cost, tough, medium-strength steel ideal for general-purpose applications, AISI 1035 is a medium-carbon alloy that can be normalized, hot-rolled, and water- or oil-quenched before tempering.
1035 steel has a chloride threshold value the critical chloride concentration above which the steel will begin to corrode four to five times higher than that of carbon steel. 1035 (HR) - Intermediate carbon higher in strength and hardness than low carbon steel. Used for studs, bolts etc. Water-hardening steels suitable for small parts of moderate strength. Used in levers, bolts, nuts, studs, and similar parts which are headed, upset, or extruded.
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good Corrosion resistance, high harness, toughness and strength.

4: AISI 1035 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.
