Alloy 4140 (AISI 4140) is one of the most popular direct hardening Cr-Mo alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel. 4140 ALLOY STEEL A193 B7 - Metal and Metallurgy Feb 06, 2010 · First, get yourself a copy of ASTM A193 and review it. Grade B7 can be supplied from 4140 steel along with other similar steel chemical compositions (like 4142, 4145, 4140H, etc.,) Melting practice, heat treatment, marking and other necessary requirements are specified in this specification.

Consideration should be given to use Mirraloy in place of certain commercial alloy and carbon steel grades including:AISI 4130, 4140, 4150, 4340, 1018, 1020 and 1045 depending upon 4140, 4142 AMS Resourcesams 6529a (4140) steel bars astm a-1031 steel, sheet & strip, heavy-thickness coils, alloy, drawing steel and structural steel, hot-rolled astm a-193 (b7, b7m)alloy-steel & stainless steel bolting materials for high-temp. service astm a-194 (7, 7m)carbon & alloy nuts for bolts for high-pressure & high-temp. service astm a-29 general requirements for carbon & alloy bars, wrought & cold-finished astm a-320 (l7, l7m, l7c)
AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has a lower tempering temperature. For example, a tensile strength of 225 ksi can be achieved by tempering at 316°C (600°F), and tensile strength of 130 ksi can be achieved by ASTM 4140 Steel 1.7225 42CrMo4 SCM440 - OTAI ASTM 4140 Steel is a Alloy Structural Steel belong to ASTM A29/A29M Steel Grade standard.
