PRODUCTION OF COLD FORGING STEEL
PURPOSE:To prevent the strain ageing of N and C and to obtain cold forging steel excellent in strain ageing resistance by applying the prescribed heat treat ment to a steel in which respective contents of C,Si, Mn, P, S, N, SolAl, B, Ti, and Fe are specified. CONSTITUTION:A steel having a compositio...

CONSTITUTION:A steel having a composition consisting of, by weight, <=0.45% C, <=0.35% Si, 0.2-2% Mn, <=0.04% P, <=0.025% S, <=100ppm N, 0.03-0.09% SolAl, either of >=0.001% B and >=0.02% Ti or a combination of <=0.0005% B and 0.01% Ti, and the balance Fe is refined. After the above steel is hot- rolled, overageing treatment is carried out at 200-500 deg.C in the course of cooling or after cooling, by which age hardening ratio is regulated to <=5% and strain ageing resistance is improved. The above age hardening ratio can be represented by an equation [where T.S' means tensile strength (kgf/mm ) of age-treated material after wiredrawing and T.S means tensile strength (kgf/mm ) in as wiredrawn state].]]></description><language>eng</language><subject>ALLOYS ; CHEMISTRY ; FERROUS OR NON-FERROUS ALLOYS ; GENERAL DEVICES FOR HEAT TREATMENT OF FERROUS OR NON-FERROUSMETALS OR ALLOYS ; MAKING METAL MALLEABLE BY DECARBURISATION, TEMPERING OR OTHERTREATMENTS ; METALLURGY ; METALLURGY OF IRON ; MODIFYING THE PHYSICAL STRUCTURE OF FERROUS METALS ; TREATMENT OF ALLOYS OR NON-FERROUS METALS</subject><creationdate>1991</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=19910809&DB=EPODOC&CC=JP&NR=H03183727A$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,776,881,25542,76289</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=19910809&DB=EPODOC&CC=JP&NR=H03183727A$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>HAGITA HEIJI</creatorcontrib><creatorcontrib>OBARA SHIGEO</creatorcontrib><title>PRODUCTION OF COLD FORGING STEEL</title><description><![CDATA[PURPOSE:To prevent the strain ageing of N and C and to obtain cold forging steel excellent in strain ageing resistance by applying the prescribed heat treat ment to a steel in which respective contents of C,Si, Mn, P, S, N, SolAl, B, Ti, and Fe are specified.
