SAE4140 42crmo4 4140 4130 1020 1045 steel round bar carbon steel round bar alloy steel bars

Alloy Steel Round Bar is made up of different material grades such as A-182, F5, F9, F11, F12, F22 & F91. These are made up of various metal alloys that are corrosion resistant and strong. Navstar Steel is a leading supplier and manufacturer of these Alloy Steel Round Bar products.

Some common applications of steel round bar includeframeworks, supports, braces, shafts, and axles. Stainless steel round bars are highly corrosion resistant. The stainless steel will tolerate high levels of acidity and can be used in chlorine bearing environments or alkaline solutions

A bar is the material which has a circular cross section which surface have unevenness or the bonding grip for concrete. A rod is the material which is even surface circular cross section.

Product Description

grade 4140 steel properties round bar

Grade 4140 round steel bar is a Chromium-Molybdenum through-hardening steel of medium hardenability. It is a general purpose high-tensile steel with medium strength level and good impact properties.
Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.
Aisi 4140 round steel bar material quenched and tempered q&t steel bar we supply includes following advangtages:
Consistent mechanical propertiesDeep mechanical properties (from surface to the center according to your requirement)
Even hardness on the whole bars/Tougher and Increased strength No brittle, UT testing/Precision size tolerance/Good straightness Good Roughness/Professional technical service/Competitive price/Fast delivery
