AISI 4140 Steel 1.7225 42CrMo4 SCM440

Admisce 4140 (AISI 4140) una ex popularibus directa obduratio Cr-Mo admiscuit laminae ferreae quae facultatem amplam duritiae et roboris evolvere habent. Elementa commixtio et curationes thermarum, ut exstinguiendi et temperandi, duritiem et robur ferri multum inducunt.
Product introduction

AISI 4140   Steel Bar, Steel Plate, Flats Supplier, Stockist et Exporter. AISI SAE 4140 mixtura chalybs est chromium molybdaeni mixturae specificatio late adhibita in generali proposito ferro distrahendo pro componentibus, sicut axes, spicula, tela, anni et alia applicationes. Similis gradus mixturae AISI 4130 chromae moly stannum chalybeum sed paulo superius carbonis contentum. Ferrum superior carbonis contentum AISI 4140 maiorem vim et calorem curationum facultates tribuit in comparatione ad ferrum AISI / ASTM 4130 mixturae, attamen naturas inferiores habet spontaneas.

5. Forging

Diligenter ferrum preheat, calorem ad 1150 oC – 1200 oC maximum, tene donec temperies per sectionem uniformis sit.
Noli infra 850 oC. Fingere operandi cudendo opus fragmentum quam lente refrigerari debet.

6. AISI 4140 Ferro Gradus Caloris Curatio

  • Annealing
    Calor ASTM 4140 ferrum ad 800 oC – 850 oC tenete, donec temperies per sectionem aequabilis est et in fornace refrigerabit.
  • Normalising
    Calefacere ferrum mixturae 4140 ad 870 oC - 900 oC, tene donec temperies sit uniformis per sectionem, macerari 10 – 15 minuta et refrigerare in aere adhuc.
  • Temperatio
    Ferrum re-calidum 4140 gradus ad 550 oC - 700 oC exigente tene donec temperies sit uniformis per sectionem, macerari 1 horae per 25 mm sectionis, et in aere adhuc refrigerare.

7. Hardening AISI Alloy Ferro (IV)CDXL

AISI stannum 4140 talea ferrea, lamina et quadrata durari possunt a frigore operando, seu calefactione et exstinguendo.

SAE 4140 mixtura ferri plerumque praeparato calore tractata ad duritiem 18-22 HRC. Si curatio ulterior caloris exigitur, calor ad 840 oC - 875 oC, tene donec temperies sit uniformis per sectionem, macerari per 10-15 minutas per 25 mm sectionem, et extingue in oleo, aqua, vel polymerum secundum exigentiam.

8. Applicationem AISI stannum circum 4140 talea ferrea

ASTM stannum 4140 talea ferrea, materia plana vel lamina adhiberi potest pro tam late varietate applicationum, ubi maior durities et resistentia adhibenda est super gradus inferiores carbonis. Applicationes typicae pro 4140 instrumentorum ferramentorum usuum includunt Componentes, Adaptores, Arbores, spoliatores, caudices possessores, bases fingunt, deiectores, dorsum et instrumenta, fixtures, tigna, formas, cams, terebro torques, axes emissiones, repagula, crankshafts, stipulae; commissuras, reamer corpora, axes, hastilia, anconia, arietes, machinae hydraulicae spicula, anni, scapulae, tormenta tormenta, catenae nexus, fusi, instrumentum corporum, instrumentum tenentium, virgas ligaturas, nexus virgas, chuck corpora, Colleta, vector paxillos & Rolls, Ejector acus, Furculas, Gears, Dux Rodes, Hydraulicas Shafts & Partes, Lathe Fusi, Logging Partes, Milling Spindles, Motor Shafts, Nuces, Termores Bars, Piniones, Pump Shafts, perforare vectes, vestigia, labitur, ligamina seu partes gerunt formans perit, fregit moritur, stringeret perit, destruit, machinamenta par- tium, etc.
